Hey guys, check out this new gadget coming out at the end of November:

[nofollow=http://www.goldcube.net]Gold Cube[/nofollow]

It concentrates a thousand pounds of dirt down to about a pound of superconcentrates with less than 1% loss of gold.  I don't know yet how much it's going to cost; have an email inquiry in to them now.   Make sure you check out how it works; pretty fascinating stuff.

Looks interesting ... but if you look at the sand they are using in their demo; it contains virtually no clay ... in the real world where quality Gold bearing river sand resides near bedrock, there's often a certain amount of clay to contend with ... I think the "trough" area of the Gold Cube may face "plugging" issues (even if the sand is classified to 8-) if being fed with sand that contains a certain minimum amount of clay ... one way around a clay-plugging effect might be to thoroughly liquify your concentrates/slurry in a bucket before adding to the Gold Cubes' slick plate... hopefully they've done some R&D with clay'ish sand and have some solutions.

I will be interested to see what their final design looks like.
I note that the material they are running is not bank run but rather classified to minus 1/4 or so.
Nothing wrong with that but it calls for pre screening and judging from the gravels in the gravel bar they are operating on the 1000 pounds of minus 1/4 will be closer to 6000 pounds or more of bank run. Thats not a negative just an observation.
Many people forget that simple screening is in fact a concentration process and can be a viable cncentration step in and of itself.
If all your gold will pass a 1/4 inch screen and you can screen off three quarters of each bank run ton you have made a 4 to 1 concentrate before you even get to the next stage of concentration.
Now in the case of the Gold Cube the time and energy and equipment to get to that screened product has not been accounted for and it should at least be acknowledged.
Once again not a negative - just the reality of operation.
It took about an hour to run the 1000 pounds of minus 1/4 through the concentrator but it could have taken six hours of hand screening to get that 1000 pounds.  The oversize ratio is highly variable so really the Gold Cube people can only talk about how long it takes to run the 1/4 inch minus if they want to compare apples to apples. How much actual production of bank run it represents will be up to the prospector to determine. In my illustration above they could have hand screened 6000 pounds to get the 1000 pounds so six hours of screening and one hour of Gold Cube equals seven hours to run 6000 pounds of bank run.
Important for the prospector to consider.

 I think the "trough" area of the Gold Cube may face "plugging" issues (even if the sand is classified to 8-) if being fed with sand that contains a certain minimum amount of clay ...


The "trough" area I speak of can be seen on this page ...

[nofollow=http://www.goldcube.net/#/complete-gold-cube/4545154829]Link[/nofollow]

... as seen on the side-view, the concentrates must navigate through three different 180 degree bends with an upward curvature ... that's the area's I think clay'ish sands could pose a plugging issue with ... as seen on the video, clean sand seems to work okay in the Gold Cube ... but I've found the high Gold grading sand occurs at the bedrock level and typically contains a fair amount of fine clay in the sand; which even after being classified, a certain amount of the sandy-clay tends to bunch together, and needs to be stirred in the bucket to create a liquid concentrate/slurry for running through a concentrator for best results.

Hello everyone and thanks for looking at the Gold Cube.  My Partner an I have been working on this device for some time now.  This summer we struck gold, so to say, with this design.  Reading some of the posts to this point has found me impressed with the knowledge base.  Let me start with a little background and then I will answer some of the questions the back ground didn't cover.

In July 2009 I was on the hunt for some beach gold on Lake Superior Michigan.  Well I found some and asked the rangers there if I could set up a power sluice to capture some.  They said it was fine but later found out I needed a permit.  I got one and went back a couple months later.  See here's how I did.  [nofollow]http://www.youtube.com/watch?v=f3ry5gHaHtA[/nofollow] Meanwhile, After finding out how difficult it was to retain very flat gold in 90% black sand, I contacted as many groups as I could to see if there was a trick to this stuff.   A couple of the groups actually led me to the information Trev had accumulated and posted.  It was great reading.  I contacted his lawyer buddy in Texas to see what the boundaries were if I came up with a device that incorporated the columning effect caused by the gated trough.  The trough idea could not be patented but the unit design could.  Looking at the pictures, we knew there needed to be some size reduction and the zig-zag design was it.  This accomplished two things.  It keeps things compact and it forces more water through the trough at a higher pressure to keep everything moving, even clay ridden material.   That being said, we also needed to find a suitable mat.  We found some incline conveyor belt that was perfect.  Since the flow in this unit is so fast, this mat had everything we needed for retention as well as being able to keep itself flushed of debris.  After quit a few prototypes and a few thousand dollars, manufacturing and patenting the design is underway.  This thing will be mule kick proof and easy to carry.   It is a recirculatable unit that will need water pumped into it.

There is a correct tool for every job.  This is not an off the bank type unit.  Everything has to be classified down to 8 minus.  Most of the gold in the world that can be seen falls into this category.   This is also where it gets tough to process.  The Gold Cube shines at the end of a day or at the end of a trip when you have many buckets of concentrates.  What will you use to get out your gold?  A Wheel?  A Bowl?  Water table?  A Pan?  If you have been working your favorite spot for a while with your dredge or power sluice, you may just have 10 or 20 buckets of concentrates.  I just picture this pile of buckets and standing there with a spoon at the ready to start feeding your machine of choice.  "I know, I'll just save it for winter!"  Now all you have to do is classify to minus 8 and run it through the Gold Cube.  Everything in that pile of buckets will be reduced to about a cup of material and now you can use your spoon with a smile.  All the larger stuff is an easy pan.  Even better, if you have a gold metal detector,  it should easily find gold 1/8" and bigger.  Just spread it out and pick up your pickers and nuggets.  So what are we missing here?  Hauling a ton of concentrates back with you, that's what.  Oh happy day!  Better mileage and more room for the dog.  

In the video on the site, There was a bit of clay but the act of classifying really broke things up.  It took us about 2 hours to fill the 16 bucket.  We classified with the bucket underwater to the rim so the material was washed pretty good.  All the concentrated material in a dredge or power sluice is washed pretty good as well.  You will also notice in the video that we were really pouring the steam to it.  We were racing the clock.   We really wanted this to fail or clog up, neither of which were achieved.  But we did complete in about an hour, I think it was actually 68 minutes.  It just kept clean and wanting more.  Earlier, we had even tried to get it to fail with 7 gallons of pure black sand in 10 minutes.  It just kept eating it!  On a side note though, the black sand was contaminated with 1/2g of gold, bummer!  The guy who brought it to us was sure he had gotten all the gold out.  We ran it again to make sure and discovered we missed 2 specks.  Truly not worth the effort of running again or saving.  

(Bill) I know this may invite more questions but we have done extensive R&D in many gold situations including Nome beach gold, Oklahoma red clay, drywash concentrates from NM, AZ and CA.  5 different locations in Colorado, and every type of material we could get our hands on.  If you have something you can't get the gold out of, I would love to try it, I'll send you back the gold.  So far the Gold Cube has not failed.  The worst that it did was back in Lake Superior, the hardest gold in the world to recover!!!  We solved the problem by adding 2 more layers.  It took our retention rate from 70% to 98%.  How did we know that?  100 pieces of gold counted and ran.  Then we counted the clean-up.  We needed to know for sure!  We have a lot of time and money in this thing.  Blood sweat tears and love and guts.  This will fill the part of the mining that has always been an issue.  The part between a pile of concentrates and you being able to see your gold.  Quick reduction without a lot of time and an acceptable minimum loss.  Such a small loss you will not be tempted to run it again or save it to run chemicals.  I have panned the Gold Cube super concentrates down to a 400 mesh.  and know it will hold them.  At the end of the video we state that we will run them again.  That is part two.  I panned the second run down to 400 as well and couldn't see any.  There were a couple 200, 100, and 50 mesh though.  About 1% as much as the first run.  It will be shown on the next video.

(Jerry)The slick plate does act like slate, When you dump the material in you can see the stratification.  It is a lot of fun to see the gold lagging behind.  Then down it goes.  Just a quick indication that, Yes, There is gold in this batch.

(GollyMrScience) As your assumption, yes there was more time involved than just the hour.  But as you have read, this is not intended to be the sole prospecting piece of equipment although it could.  The Gold Cube is intended to super concentrate after a dredge or power sluice etc.  That is where it will excel!  It is wise to point out material preparation as part of the time a miner spends but the bottom line is, when you grab a shovel and pick, it's work.  Whatever machine you run it through you will be left with the good stuff.  Your gold is in there somewhere.  If you are a hard worker or if you have a lot of help, you are going to have a lot concentrates.  typically at a ratio of 40:1  the more you move the more you get.  Our experiment on tape was about volume.  The gold was a nice bonus.  Man! could you imagine if we had been dredging and had all those bucket?  Whew!!!!!!!!  I need to sit down!!  Thanks for your factual mind.

(Deserdog)  Yes, this is a forced version of the same principle Trev shared with us.  Them old miners were smart, we are smart to learn from them.

(Lonetree) I'll put your name on one.

Please feel free to contact me.  I'll answer any questions.  I'm really proud of what has been accomplished an you guys are a jury of my peers.  I thank you for that.

Mike

Thanks for the input Mike. I thought I recognized the matting. Have been using it on fine gold concentrators for over 20 years and it is amazing what it can recover from classified materials.
Please know that I am not offering the observations as a critique but rather an inclusive approach. So many prospectors want one machine to do it all. Heck we all do. It has to be able to handle bank run rock, smaller than a bread box, weigh less than 15 pounds and process tonnes per hour running off a 12 volt water pump and every hour it should go "Ka Chinnnnggggg" and a bar of pure gold will fall out.
It is very important for people to realize that they have to consider what they are using as part of a system. Not ask it to do something it was not designed to do and give it what it needs to do its job. Recognizing that will prevent disappointment and keep expectations realistic. Part of that is the responsibility of the manufacturers to give people enough info to be realistic in their expectations but part of it is also up to the prospector to BE realistic. Lets face it its a lot more fun to be UNrealistic but not nearly as profitable.
If for instance 8 mesh is what the Gold Cube needs then give it 8 mesh and if a prospector thinks getting 8 mesh is a pain to do with a hand screen and if the Gold Cube is the concentrator they plan on using they should be working on designing a screening system to make that part easier as that is the true bottleneck not the Gold Cube.

Hi Mike ... as Jerry says; this product bares watching.

In BC, particularly on the Fraser River ... sand on the top of a sand bar is very clean, and works well in basically any type of concentrator ... but when you dig down through the sand and hit bedrock, you'll get fine clay mixed in with the sand (this layer also happens to be where most of the Placer Gold is found), this fine clay will occasionally bunch/clump the sand together in small clumps as it's washed through any type of concentrator ... there's a couple High-Banker manufacturers in BC who have experienced this, and thus they make extra efforts in their Hopper designs to provide an extra wash effect for breaking up the clay-bunching/clumping effect.

Some people use "clay buster" or "clay gone" additives to break up the clay effect when washing through their concentrator. The clay is something we have to deal with once we hit the clay layer that sits on the bedrock layer.... as mentioned above, sand sitting on the top of a sand bar is clean and contains virtually no clay, however, the majority of the Gold sits on the bedrock layer and it's typically encrusted/surrounded in a mushy sand/clay layer.

Do you have a projected cost for one of your units yet?

Bill I feel your pain.  I have gotten into some real good areas that just got better the closer to the greasy bedrock we went.  We were shoveling into a power sluice and just kind of quit at the clay.  We took a break for lunch and talked about it a bit and then when we started back up, we sampled the clay.  Holi poop!  It had the best gold of the day.  We tried to wash and scrub it the best we could but what we ended up doing was to put 2 gallons in a 5 gallon bucket and fill the rest of it with water.  We let them sit over night and stirred them real good.  It was pretty soupy but it wasn't clumpy.  It ran just fine trough the power sluice.  That was before the gold cube, I wish i would have had it then.  The water runs at a 15º angle so the mat is always working.  This really keeps the gold pushed down and the light stuff flushed off.  I haven't had a chance to get back to that location so I used the red brick clay here in Oklahoma.  I gathered what I needed for a test and went to making a mess.  I actually found the best way to keep the production moving was to use a mud paddle or paint stirrer.  the kind that fits a 1/2" drill is the best.  It really cuts the clay to a nice sloppy mess.  In about 5 minutes you will have all the chunks rendered down to a soup.  If there is gold it will process just fine.  In the case of Okie gold?  Zip on this experiment.  I did have black sand though.  The Gold Cube ran this rich slurry without a problem.  But as you can see, clay just means you will have to add a step or two no matter what machine you choose to use.  Now where this machine will really help is after the clean-up of a dredge or power sluice.  Those boiler box. com sluices will really break up the clay and you would feel more comfortable doing more frequent cleanups to keep from washing out the fine gold if you had a Gold Cube.  The Gold Cube will take all the cons you could gather in a week and reduce them down to a cup in a few minutes.  That is quite a bit easier to carry out than 10 buckets plus.  Bottom line though that we have found,  If it goes down the trough out of sight, it will not clog the unit.  8 mesh- is it's happy point.  treat it right, and it will return the favor in gold.    Oh and pricing?  We are close to revealing it.  We are working out some details with some wholesalers.  Should have a number for everyone at the end of the week.  Thank you so much for your interest, please keep the questions coming, We have tried to think of everything, but are always willing to learn.

That's right.  800 is a must but we will be selling 1100 GPH pumps.  Better to have a little extra water than not enough.

Looks very interesting Okie and glad to see someone finally work with Trev's Treatise On Fine Gold Recovery.  Good on you for giving credit due as well.

You seem to have done an excellent job of taking it to the next step with a lot of testing and re-design to bring it to this marketable stage.  I wish you great success with it.

I am of the school that likes multi recovery media types in my equipment.  Will it be possible to buy partial units that can be incorporated into an existing highbanker.  For instance I have a great shovel in hopper with recovery and screening area. Could this be added below the screen so that a material handling step is reduced?

What would be the max water flow for the Gold Cube? In the above example, the shovel hopper likely has more than 1100gpm (although I could turn it down a bit) - would this overwhelm the Gold Cube trays or would the excess water simply overflow the top?

It's interesting to note that your experiments found a curved bottom to be best instead of the horizontal flat bottom that Trev used. In our early discussions on Goldminers I always wondered about that but never did try experimenting. Kudo's to you and your partners for working through the whole process..  Looking forward to seeing the pricing/S&H details.

Hello Mike!

...And as for completing the rest of my first time introductions, a big hello to all of the regulars who post in CGP Forums, as an avid reader of the forum, your shared experiences help educate others like myself who know little, but can read lots.  As I exhaust night after night of reading, it seems that somehow sub-topically, google always leads back to gpex.ca forums. Whether one is looking for equipment knowledge, mining techniques, or types of mining... gpex.ca forums. :)

Well Mike, what prompts my question under your Gold Cube Technology thread is a few questions still up in the air about Gold Cube as a potential customer to be...

1.  The maximum effective water/slurry in-flow (pump included at 1100 gpm) that can be achieved before the vortex matting starts to effectively degrade.  From the limited video available on your beta testing and modeling, one can see certain elements of the Gold Cube system that have progressed through tweaks and flow refinement.  Has anyone with hydrostatic flow dynamics or fluid dynamics reviewed the gold cube design that you and your partner created?  From following your video clips of your path of development, and the various postings on gold cube here in gpex.ca forums, am I to understand that the gold cube pump is best reduced 50% and the slope decreased from 1"/12" by 1/4" when focusing on gold smaller than 100 mesh?  

2. If a prospector works a region that has predominately river or creek basin of aggregate, sand, clay, and silt that is gold bearing; the current role of gold cube would be a finishing step, post initial classification.  Is there any consideration for gold cube to be further expanded to host a classifying hopper?  Larger than 1/2" slides down a rod classifier off the side of gold cube via smooth sluice (or  classifier rod extensions), next layer uses expanded metal at a 30° slope towards spray edge of the slant top of the cube, and classifies to 1/4" and adds water to concentrate, oversize concentrate goes off other side of cube via smooth sluice. Last stage of rod classifiers down to 1/8" and feeds cube slant slope.  Each classifier level could be another 'tray' of the cube design; a system could be as small as your single sluice tray, or as complex as a big model of 6 or 7 frames high; top slide-off classifier (expanded metal insert, 1/2" to 1/8") up to 2 classifier trays, slant entry tray to sluices, 2 sluice, base tray.  The vacuum-form plastic could be used to hold the classifier rods and inter-changable expanded metal classifying panels in any classifying tray.  The spray bar of the hopper could be split on up to two levels of classifying action as a U-type spray bar, each tray with a valve that would allow variable pressure to that classifier section.   Such expansion modules would make the gold cube as a one-stop back pack solution for close to 40:1 concentration at a lift of a shovel full in limited water source work.  The designed trough may have to be expanded by 1/4" to allow for the extra gph water-works with the classification sections to come down, slope may have to be dropped another 1/4" or riffle height adjusted between trays on multiple sluice tray models. I guess you can tell I would like to see the gold cube expanded to classify larger materials in some fashion.  Generally, for most applications, using the cube will involve the the use of a rotapan, or highbanker, or river sluice, and then those classified materials 1/4" into the cube. It would be nice to be able to run 2 sluice trays, a 1/4" classifier tray, and 1/2" classifier sloped top tray, and have the cube as a one-stop 'out-in-the-claim' solution from the shovel to the spiral wheel or finishing sluice.

3. On the point of gph load of the system; the current gold cube pump is 1100gpm.  Can the cube handle a 4:1 venturi suction dredge primed by a 1-1/2" 160-220 gph gas pump, which would be a 4" column of water & 1/4" concentrate ?  Would the cube handle the concentrates and water of a 3100 gph marina pump sucking up 1/4" concentrate?   If there a future model that can handle higher volumes?   Such as models that are 24" or 36" wide.  These models would be more application specific, such as 1/4" or 1/8" classified suction dredging; possibly a beach gold model that offers a 1/4" expanded metal sloped classifier top, and a full 36" width so two men could should sand-like concentrate onto the cube classifier or slant tray, and the cube would be able to keep up.   Doubling width would double water demands, so now you would have a 1100, 2200, 3300-gph models.   Considering fabrication method of the cube, all of these feature considerations (wish-list items) could be easily integrated; compared to other processing systems that are less inter-changable, and more the sum of their parts.

Yes, I've really been reading way too much lately. :)  But one last point...  
 
4. Black sand,  the vortex matting is designed to do a great job of creating multiple low pressure vortex which trap gold, and in time, gold pushes out black sand.   The black sand comes out into the recirculation pool.    Now, I'm still really new to prospecting, but if a person is trying to retain 100% gold 'processed' from hard work, then should a prospector be sending in the gold bearing black sand to be further processed at a metallurgist or lab.  My understanding is that gold bearing black sand, like bench or river sand that has 100 mesh & finer gold can be processed to remove the >200 micron and nano gold out of the black sand.  That black sand in those conditions can hold as much as a 10-20g worth of gold per pound.  So that's still a few $hundred$ towards the prospecting hobby and expeditions from the gold in black sand.  I ran across that through a posting from a jeweler who will process gold bearing black sand for 10-15% of value.  That they will do a assay batch to give you an idea of the value of your black sand.   If one wants to leech the gold from black sand, then the gold cube is too efficient.  The black sand (most) comes out the bottom edge, right?    Well, here is a custom tweak I wanted your thoughts on...   In desiring to further process black sand, if I wanted to retain as much of it as possible;  could I just add a magnetic strip to say, the bottom sluice tray of a 4 tray system?  Then that magentic strip taped to the bottom of the lowest sluice tray, at a point where most or all of the gold has been stopped further up; the magnetic strip would draw the black sand to the bottom of the sluice, and with the back sand drawn there, the vortex matting would have a harder time maintaining the low pressure areas - but most the gold is in the upper tray to begin with, and the magentic stripe is at the bottom of the 2nd sluice, just before dropping into the lower tray.   Would this custom add-on make black gold gather at that point?  With black gold gathering at that point, would it not further infuse with below-eye-site micron and nano gold particles flowing through the black sand build up?   A question I have been trying to analyze.  As I would also like to process the black sand for the extra $100 per pound of black sand to help offset the cost of hobby prospecting.    

5.  Top Classifier & Spray Hose Nozzle.  The top of the cube could be a 1/4" classifier, or again inter-changable size down to 1/8".  A manifold would allow a 3/4" garden hose to connect to the water, and a ball-valve would allow controlling the hose feed.  One could wash through the concentrate sitting on the classifier top of the cube.  Some sort of slope or chute may be necessary.

6. Dry concentrate vacuum cube top - having a top tray that can be mounted over the slant/feed tray of the cube.  On top of that vac-form mold is a spiral flair shoot for even distribution onto the wash tray.  Top of the tray is the connection for a 12v squirrel cage leaf-blower-like motor (high cfm) that would allow a prospector to 'vacuum' up wet/dry concentrate, with a screen to 1/4" and the excess/over-sized blown off through a refuge hose flare.  This would allow easy loading of dry concentrates, combing black sand on beaches and sand bars.  And with accessories and hoes extension (reduced for added suction), a crevice sucker add-on for the vacuum-top.   The 1/4" classifier of the vacuum top  could be in a bowl shape with spraybar water-works.  With the proper alterations, maybe moving to a 24" width, the motor on top could be setup to pull the 4" column of water using a jet-like nozzle setup on the suction to feed the cube.  Cube just has to be able to handle the load.

I also noticed that talk about the gold cube has quieted down since November.  Of course a big portion of that is all prospectors are hibernating for another few months.  Are you now into production?  Are you actively selling the cube now?  I have visited the website, and I am considering ordering.  I wanted to know if there is a manufacturing lag-time involved?  How long does delivery take?  Do any of the options I have mentioned sound like something that could be 'added'?   I realize the slope of classifiers, and need to expel the over-size burden makes some things more challenging. But using a vac-form shell, a classifier poop  chute could easily be added in, even vac-form trays with classifiers built right into the trays. Angles will likely be an issue to address. The water works system design, etc.   I believe quite possible and economical to add as expansions to the gold cube package.

I'm about ready to order your 4 tray package, with pump, stand, hose.  I know the cube will be put to the test here.  Gold is a rare item where I live and will be practicing with the cube, so I will be ready to use the cube with some proficiency at tweaking its setup by this spring. During my practice runs, the cube will have to cling onto every 200 mesh particle passing, so if I find gold around home with the cube; then I know it will do well out on my claim later this season :)   Around home I have a few streams to test, couple river sand bars, and three gravel crushing pits...  lots to practice on.  I want to see how it interacts with the various densities of the materials from each area.

I am curious to know how the current 4 tray package will handle 1/4" screen suction dredging.  How many gph could be added to the current 1100gph flow?  Cut flow in 1/2 and one is safe to feed a 1-1/2 section dredge feed of 1/8" concentrate?  If it will handle the volume what is the best way to add the dredging hose feed to the cube?  Would (could) you make a custom top for the cube that would take a 1-1/2 concentrate feed and fan it across the slant tray for processing?   If you could make such a dredge feed or fan top for the cube, what would it cost?

Look forward to learning more about the gold cube. I was going to order yesterday, but I thought I better throw my questions out there first, and see what kind of answers there are. Being a new technology design, I can understand not having all the answers at this point in time, as some only come with time and exposure of use.  gpex.ca forums was the only place I could really find an interactive forum with you folks regarding your project and the gold cube you offer today.

Cheers! And great job on the Gold Cube  <-good_>

Post by: Okie on January 30, 2011, 11:01:06 AM
Great questions and suggestions k0diak. The Gold Cube was born from frustrations and refusal to use old technology that wasn't working for the material we found on beaches of Lake Superior Michigan.   You, I see, also think beyond the box and want to achieve more than status quo. 

Let's start out with a quick up-date on Gold Cube as a company.  We have product in stock and will ship within 24 hrs of the order.  There are quite a few Cubes out there and have been getting some pretty good feedback from them.  The best was from New Zealand and will be trying to get permission to use the photos of 1.2 oz of minus 50 mesh gold seen within the first 3 inches of the first tray.  I will post that as soon as I can.  We have been on the road for the last 3 weeks attending the GPAA gold shows in TX, AZ, and CAL.  We really caused a buzz and are looking forward to another round of 4 shows in March and April.  This is really a fun ride we started.  Soon on the site we will be posting better videos as well as testimonials.  Keep watching. 

1.  Has anyone with hydrostatic flow dynamics or fluid dynamics reviewed the gold cube design that you and your partner created?  Nobody with a degree has.  All our test were done with real life.  We used 100 pounds of black sand and 100 pieces of gold.  The hardest material we could find was on Lake Superior and that was the test material we used to fine tune the Cube as well as test every other piece of marketed equipment we could get our hands on.  All other material we have been able to obtain, including Nome beach sand, has been a piece of cake comparably.  The angle that allows the vortex mat to create little quicksand pockets is 15º, there is nothing to adjust or tweak.  When you shoot the water high enough on the exit of the G-force separator, it creates a low pressure zone that sucks in the gold hard.  This zone lasts for around 3 inches.  After that it will still hold gold but no better than a sluice and no worse.  On one cleanup a customer found 1.2 oz of gold or 527 grains.  The top tray had 517 grains, the middle had 10.7 grains and the bottom only had .2 grains.  So you can see that the need for adding trays will decrease the further down you get.  Over 90% of the gold in your cleanup will be in the first tray.  The water flow we have used in the cube that work well are 700 GPH all the way to 2000 GPH.  The 1100 GPH we are running with a 1.125 hose fit over a 3/4" fitting at the water box.  This does create a restriction but the result is a good water flow with less spillage.  the Gold Cube will handle more water and work very well.  The real rate control is the point that it drops straight down into the G-force separator.  Too fast and it could back up.  The more water you are able to feed this thing, the longer we will be able to make the low pressure zone on the Vortex mat that means more gold trapped sooner in the process. 

2.  Is there any consideration for gold cube to be further expanded to host a classifying hopper?  I guess you can tell I would like to see the gold cube expanded to classify larger materials in some fashion.  As you have noted, the Gold Cube will run material from 8 mesh and down to powder.  We have measured gold down to 400mesh and have run 400 mesh pulverized load material for a customer in Mesa AZ.  Needless to say, he was impressed and purchased a 4 stack unit.  When we made the Gold Cube we were focused on the gold that everyone was having a hard time collecting.   Almost every piece of equipment out there will easily capture 1/8" and larger, that's the easy stuff!  If you were to run 1/8" classifier rods on exit of another piece of equipment and then run all that classified material through the gold cube, you will effectively capture the gold that was blown out of said piece of equipment.  We are currently working on collector that will attach to anything and auto feed the Gold Cube.  That is vague I know but you are wanting what we are wanting, "shovel ready"  We are not working on a version at this time that will process 1/8" plus.

3. On the point of gph load of the system; the current gold cube pump is 1100gpm.  Can the cube handle a 4:1 venturi suction dredge primed by a 1-1/2" 160-220 gph gas pump, which would be a 4" column of water & 1/4" concentrate ? The Gold Cube can handle a proportional percentage of water and dirt of 1/8" minus material coming from the hose.  It will have to be separated via a grizzly.  The full force of 4" of water would probably tip the whole unit over.   As in question 2. pull out the 8 mesh minus and let something else pull the nuggets.  We are working on a post dredge separator as well.

3.  Black Sand  if a person is trying to retain 100% gold 'processed' from hard work, then should a prospector be sending in the gold bearing black sand to be further processed at a metallurgist or lab. ..............black sand in those conditions can hold as much as a 10-20g worth of gold per pound.  In desiring to further process black sand, if I wanted to retain as much of it as possible;  could I just add a magnetic strip to say, the bottom sluice tray of a 4 tray system?  I am sure there are areas that you will find black sand that is really black gold.  In this case the weight of this will allow it to stay in the Cube.  It will hunker down with the gold and mess with you at clean-up.  I have gone down the path of grinding, cooking, fracturing, leaching etc etc etc.  I have never retrieved more gold than the process cost even if my time was free.  If you are aware of your material and have seen alot of locked up gold then save it.  The cube will hold that for you anyway.  Other than that, black sands are tailings.  If you want to collect the black sands use your magnets at the discharge of the material, not within the cube.  If you put a sluice at the discharge end, it will catch a bunch of them.  While you are there pan it all out and see if you find any gold.  We did and found out it was a huge waste of time.

5. noted

6. Dry concentrate vacuum cube top - having a top tray that can be mounted over the slant/feed tray of the cube.  Wet dry or sticky can be scooped into the Gold Cube.  All material is forced underwater so no surfactant is needed and all floating gold is ripped away from surface tension and pulled under water.  It will never see surface again until you do a clean-up.  Don't pre-wet and don't give you unit a bubble bath when recirculating.  1/8' minus and raw water is all that is needed.  I am curious to know how the current 4 tray package will handle 1/4" screen suction dredging.  How many gph could be added to the current 1100gph flow?  Cut flow in 1/2 and one is safe to feed a 1-1/2 section dredge feed of 1/8" concentrate?  If it will handle the volume what is the best way to add the dredging hose feed to the cube?  Would (could) you make a custom top for the cube that would take a 1-1/2 concentrate feed and fan it across the slant tray for processing?   If you could make such a dredge feed or fan top for the cube, what would it cost?  1/4" material will roll right over the mat in the separation trays, you will be wasting you time there.  If you feed the material with a slurry from a hose, it is best to have the material splash against a box plate that will spread it out for better dispersion.  Watch the flow dropping down the trough and adjust the flow to keep it from backing up.   

Thanks so much for the questions, I am a 2 finger typer so this took a while.  I hope this answered some questions.  If there are more questions feel free to ask.  I'm here for ya.  We consulted a lot of smart people Trev to name one.  We got this thing figured out.

Afternoon Mike!

Thank you very much for your fast 'two-finger typing' response to my list of gold cube questions. 

Your answers have helped me understand the gold cube operation better.   

I will be watching the future development of gold cube add-ons. :)

How many gallons of water should the recirculating pool/tub hold to run the gold cube efficiently?  Just an idea to figure out how big of a container to purchase for the gold cube system.  What is the width of the gold cube?  Again, considering pan or pail size to operate the cube within.   You also have mentioned that a sloped bottom for the recirculating pump is better than a flat right-angle bottom on the recirculating pool/bin? How much of a slope works best?

I assume that the pump has gator-clips to connect to batter posts?  What about battery sizing?  How many amps does the the 1100 gph pump use?  This will help me calculate my Amp Hour needs in sizing the battery to run 4, 6, 8, 12 hrs without needing to be recharged. The deep cycle batteries are ideal for this application, wear better, but they are quiet expensive as an initial investment.

The water flow we have used in the cube that work well are 700 GPH all the way to 2000 GPH.  The 1100 GPH we are running with a 1.125 hose fit over a 3/4" fitting at the water box.  This does create a restriction but the result is a good water flow with less spillage.

Water volumes. Ok, so as low as 700gph, for an area known for micron gold, such as your Lake Superior test; this would assure the finer stuff is not flushed through.  Although it seems 90+% is always in the first tray, so on a 4 tray system, you have extra processing footage that is not seeing (much) gold, if any.  Or would it be that the 2000gph is better for micron gold?

As the higher volume rates would cause a stronger g-force coming out of each trough between trays, and force even the smaller stuff into the vortex matting?   I guess what I am saying is that I can rationalize fine gold collection at both ends of the spectrum when it comes to water flow.   Slower makes for gravity to take effect, and at faster volumes it would cause the g-force troughs to push the micron gold against and down into the vortex matting.   So what have people found so far?  What scenarios are best for each low, and high volume water travelling through the cube?   Is there a ball-valve up at the spray bar connection to controll the flow rate, or would that have to be a customization of the system itself by the customer?   

I assume with the 90+% being found in the first tray, many would option for a 3 tray system.  Would I be correct in thinking that in using a 4 tray system, the prospector then has a longer period of classifying and feeding the gold cube before having to clean the sluices, etc?  That in a 4 tray system, as the 1st tray becomes full or operationally impaired due to overload of classifieds, then the 2nd tray starts taking up the slack, which when full would push the 3rd tray into action.  So really by going a 4 tray system, the prospector is expanding tha amount of time between cleaning sessions of the gold cube?  What is the value and benefits for the extra $120 or so in upgrading to the 4 tray model?

In trying to capture smaller than 400 mesh, would the addition of grit-tape into the cube process at some point, say the lowest g-force trough, help with the collection of 400+ mesh gold particles?  I bring this up because I'm going to be gravel pit tailings and crush concentrates as samples from close-to-home areas that are not rightfully known for having gold. I guess it would be the next next step in extreme micron prospecting, after your Lake Superior sampling.   Not that I plan on working this area, just that it is close to home; So it allows me to become familiar with, and fine-tune gold cube operations before spring arrives and I'm off traveling to the gold bearing mountains :)  I figure if I can practice collecting 200 mesh and smaller locally, I should have a good feel of the cube's operations for my first trip to the gold bearing areas in May.  I'll be documenting my practice runs locally, so I'll share any findings I have from those experiences.

Shipping to customers;  Am I correct in assuming the gold cube is shipped in an ordinary cardboard box, and that there is no identification of what is in the box, such as 'Gold Cube" or "Prospecting Equipment" or such on the outside fo the shipping box?  I bring this up out of curiousity of how the local post office employees would forsee the shipment.  Will they be able to read/tell that I've ordered in prospecting equipment, or will it look like just another brown cardboard box that could have anything inside it?  In small communities, confidentiality of what one does purchase is a bit of a concern.  Bad enough the neighbours know what I am doing in my yard, when I leave home, when go vacationing;  I would prefer that they don't know about my hobbies.  Right now most suspect I love higway touring and go on driving holidays, they don't need to know that I am actually crazy enough to be up to my kester in cold glacier water with a bad case of gold fever and prospecting the daylight away :) heh.

Again, thank you Mike, you have been a huge help in expanding my understanding of the gold cube system. And a thanks out to your partner on the project, and all of those who have consulted & beta-tested for you.. the collective input shows in the cube's design. Once you have had a chance to reply and I've reviewed your comments, I will email you directly when I place my order at the Gold Cube (http://www.goldcube.net) website.

Thanks again!  {-applause-}

k0diak,
In the 1000 pound video we went through 15 gallons of water.  We captured all the material in a pan set in the water.  As the pan filled with material, we would take it out and put in an empty one.  Keeping recirculated water clean for our material was pretty easy, it was river wash material that was washed as we classified.  If you are running material with silt or clay you will need to do as you would with any recirc operation.  Use one tub set the Cube into, have it overflow into another tub.  Have that one overflow into another and pump from that tub.  This multi step water set-up will give the silt a chance to settle out and keep your water better, longer.  So your water requirements will depend on your material. 

The 1100 GPH pumps we use draw at 3 amps 12v I have used a pump for 4 hours a day 5 days in a row in fact just this past month I did it.  After I was ready to pull out my neighbor in the next lot was having trouble getting his slide-out back in.  He need to replace his whole control unit.  I crawled under the unit space and disconnected the wires and ran some new wires out an access hole.  We connected the leads to the same battery we were using and it slid back in like a dream.  It didn't seem like the battery was low at all.  It was a deep cycle battery, about 4 years old, must have got a good one.  If you are going to be off the grid you could get a small solar cell to prolong the battery life.  As for clips, I should supply them but at this point I don't.  I'll look into a good source, thanks.

Water flow has a range of effectiveness, below 700 is iffy.  past 2200 is unknown.  Everything in between works with not much noticeable or measurable difference.  The 1100 GPH pump is the sweet spot.  If you pump more water will splash around but will still work to process the gold.  Just don't get crazy with a 2000 in the living room.   [email protected]

3 or 4 tray choices fall to the gold you are getting.  If it is flat like a coin, stack-able at any size, you will need a 4 stack.  The gold on Lake Superior was 85% to the 3rd stack and 98% to the 4th.  It was flat like glitter though.  If you gold is close to the source and chunky then all you would need is a 3 stack.  If you don't know what you will be getting into then you will probably feel safer with a 4 stack.  Just calculated the results from my customer in New Zealand.  His clean-up of 1.2 oz had 30 cents of gold in the last tray.  He would have to process 394oz to pay for the tray.  On lake Superior 13% of the gold was on the last tray.  If I did a 1.2 oz run I would pay for the tray in 1 run.  Your gold shape is the deciding factor. 

-400 mesh aaaaaaaa?    Tough stuff!  We do pretty good with the 1100 set-up but smaller than that I have no idea.  I would like to know what you find with yours. 

Yup a plain brown wrapper, I'll <-sealed_> keep it a secret.

Thanks again

Mike

I will do my best to keep the living room carpets dry, I promise!  ;D    - And I will pick up a set of DC gator clips for the battery connection at a box-store the next time I am in town.

This helps me out a lot, thank you.  At this point I guess we'll just sample and see where/if gold appears :)

-400 mesh aaaaaaaa?    Tough stuff!  We do pretty good with the 1100 set-up but smaller than that I have no idea.  I would like to know what you find with yours. 

Yes, below 400 mesh is darn micro-small to 'look' for.  But considerign the history of this region, chances are, at best, that is what we will run across, is smaller than 200 mesh flour.  This is why I asked, otherwise, if I were in BC or such, I wouldn't be so tentative to anything smaller than 400 mesh.

Yup a plain brown wrapper, I'll <-sealed_> keep it a secret.

Great to hear about the basic plain-jane shipping box/wrapping, Mike.  I just came back from the goldcube.net website and picked up a 4-tray package.  Now just to impatiently sit and wait for it to arrive :)  My prospecting partner is hot on the game...  He wants to go collect concentrate this week, so we'll have something to run through the cube when it arrives... lol!

Thanks again for all your product support :) We look forward to the cube package arriving.

Hello Mike
I have been following this thread with growing interest and enthusiasm. If anyone could have a better application for the Goldcube than I; I would like to see it.
I am on the north coast of British Columbia, Canada and have just about went around the bend trying to separate micron gold from black sand found on our beaches after storms. I have to laugh at the idea of screening to -8 mesh; there is not a thing in this deposit that will not pass through a 100 mesh screen. It is difficult to tell how small the gold is although I am convinced that it is smaller than the black sand, as the black sand is smaller than blonde sands found beneath the black sand deposits.
I had contemplated attempting to separate gold from black sand by screening (either through 120 or 150 mesh screen) but found that screening through such minute pores is tedious, to say the least. Paninng this material is an exercise in futility, as well. How anyone can productively pan -150 mesh gold is beyond me.
That being said, I visited your website to find out more about the Goldcube. Like deserdog, I immediately recognized the technology from the New Zealand boilerbox. I was impressed with it when Trevor first shared it with us but recall thinking it would be a difficult thing to carve on a piece of plywood, so I gave it no further thought at the time.
If it turns out my gold is all flat and -200 mesh, do you think the Goldcube has a good chance of recovering +95% of it? Also, at this minute particle size, perhaps you could elaborate on the cleanup process with the Goldcube.
Regards
Bob

It sounds like your sand is close to the same sand I found in Lake Superior.  The smaller the tougher, that's for sure.  Trev is a wise man, that boiler box of his was a real inspiration.  Do you have any pictures of your gold sand?

I think user greg in BC asked it in the previous page, and it has sort has been answered with the flow rate questions.... but in short, can your system be added to the trailings off something like the boilerbox.ca using their recommended gas pump. The setup i am looking at is a highbanker that runs into the gold cube. a one step process, of shoveling in and capturing most or all of the good stuff. So, do you think a highbanker will perform with the gold cube if something like a 1/8 grizzly or screener was added to the trailings of the highbanker running into the gold cube....???

Or would your suggestion be to just run the highbanker and take its concentrate after cleanup and run it through the the gold cube (given it is 8 mesh and under), being that the the highbanker will capture most if not all of the precious metals in the first-place, and the trailings off something like the boilerbox's will contain next to nil.

Cool unit though, looks like it can withstand the beatings the bush will make it endure, and the price is right IMO. little steep but worth it if it works. Couple more poegy checks saved up and were in business buddy! lol.

We are currently working on a device that will capture all the #8 minus and send it into the Gold Cube.  There is going to be way too much water so part of the device is a flow splitter you would be able to adjust.  This should allow it to work in conditions of 13 GPM all the way to 100 GPM.    Meanwhile if you want to classify after the highbanker and and bucket it into the Gold Cube that would work.  If you have a small highbanker it may just flow right into the Cube.  The bottom 2 lines are 8 mesh minus and water will only go down the Gold Cube just so fast.  If it is splashing and backing up, you will need to slow the water down.  We used it after my Keene highbanker.  Every angle and water flow we used it, the Gold Cube was able to capture missed gold.  I really thought I was doing better than that with the highbanker.  I think you are on the right track with the combination.  The ability to wash your rocks and then keep the chunky stuff in the sluice.  Followed by the Gold Cube to capture the flat small gold that flipped out.  I will have this device out this summer.  I will keep you all informed.
As for the concentrates from the highbanker, The Gold Cube will be able to take your concentrates down to about a cup and a half of super concentrates.  If you are used to taking home many buckets of concentrates, you won't have to anymore.  Classify them down, pan out the big-easy stuff or run over it with a metal detector.  Then -8 will go through the cube.  The Cube will hold over 5 OZ of gold, wouldn't that be a great trip!!   
Hope this answered your questions, I kind of went on and on.  Happy Prospecting

Mike

Howdy Traveller,
Since I spend much of my time handling fine and micro gold in black sand for myself and my customers, I typically pan 100- 200 mesh gold regularly. What do I use? A $20 Maverick Finishing Pan. Is it hard to do? Not if you know how. Using a so called regular type pan doesn't cut it very well unless you have had mucho practice. I know only a few that can do it efficiently with standard pans. Cheers.

One thing is for sure... you got to go slow to recover 100-200 mesh gold in a regular pan! How about gold below 200 with a regular pan... possible?
Yes... but, not many people will work one pan for over 5 minutes! <-laugh->

There are a couple of rules to panning, The first and most important is, if everything in your pan is the same size, gold wins!  The second is cut out the middle man.  Magnetite is the middle man, get him out and you will be left with heavy gold and light stuff.  It makes for an easy pan at any size.  There is nothing cooler than to see a 400 mesh smiley face in your pan.  If I am after the small stuff, I dry everything and classify it down 8, 12, 25, 50, 70, 100, 200, 400 then I remove the black sand.  I leave the black sand in as long as possible to be able to knock things around enough to free everything from the gold.  After you take a magnet to each size, then pan everything out.  Oh what fun!  Each pan should take no more than 2 minutes.  I use 2 gold pans to pan out the fine stuff.  Using one as a safety pan then switch and re-pan again then switch again.  Usually by the third pan there's nothing left that looks like gold.  Pan the next batch.  Have fun with it

Mike,

Some very good advise!

One problem with this little creek... the black sand wasn't magnetite, 90% was the cousin, hematite. And even using a neodymium magnet would only pull very little material! No problem... 500 mesh gold is only .001"! [email protected]*

Only about 50 to 60 % of the black sand in a creek I work is able to be removed with a magnet. I wish it could all be removed so easily!!

Well I promised Mike I would give feedback on my use of the Gold Cube so here is what I have so  far. I have no relationship to the Gold Cube in any way other than buying one.

I have only had a couple chances to run my Gold Cube on some stored cons but have found it to be very efficient.

As mentioned it is very fast and so far I am not finding much to speak of in tailings.

What I like is I can set up my 5 yr old to feed it and not worry about it being overfed. Just as they advertise - no teaspoon feeding here :7 I haven't done a scientific comparison to a micro sluice/CA bucket sluice etc but it seems to be at least equal if not better at the fine gold - but you can push material through MUCH faster.

I did not receive or hear about any "clips" for the spreader bar.  Any pics or more explanation of what these are and how they work?

The spreader is one of my few negatives for this unit.  Great idea but seems like an afterthought.

As I mentioned my spreader came so it just fits loose on the built in shelves.  Water pressure pushes it out of place so water sprays all over.  Need to hold it in place with some large clamps - kind of works but is not professional. This needs a second look for the design.

I would prefer taller walls around the water input and then an adjustable gate. You could add or remove the mat to spread the water and the mat would be easier to wash out.  To my mind this would give more option for spreading the water and may work when feeding undersize as an undercurrent from a sluice or trommel.

Also the mat used to spread the water gets plugged with things.  I am running cons that have been around for many years and have had dog hair and sawdust added to them.  Even after screening to 1/8" there is enough left to clog the carpet which slows the flow and puts backpressure so the water pushes out around the spreader plate.

Regarding the main mat I too found many 'dry' holes after a couple of lengthy runs (once was like 50% of the holes were dry) - might just be our water is highly mineralized?.  I was cncerned that if they were still dry after that much slurry flow then gold would never sit into them.  I now start by pre wetting each tray as I stack them.  Put a little jet dry in some water, pour it on and work all the air bubbles out with a small brush or my hand. After the first (bottom) tray is all wetted I place the next tray on and do the same then set the feeder tray on (3 stack) and go to work. Only takes a couple minutes.

No need to worry if you have some extra soap and are getting bubbles/foam in you main water as the spreader and the gravity gates negate any bubbles that get past the pump.

The trays are easy and quick to clean up although once the gold gets in the bottom of the holes it does like to stay there - which is a good thing. ;-)

I would like to see it come with an extra couple feet of water hose for the pumps so that you can easily set up your recycling system and keep the pump away from the tails. 

I think it would also be proper to supply the pump with some battery clips so you don't have to go out and pick some up before you can get it going.  IMHO you should be able to open the box and start working - not have to go shopping.  It's not a big deal but it should come complete.  I also ended up adding some length to the battery wires so I could have some options on where to have the battery.

One thing I think the manuf should look at is designing a new feeder tray.  Currently it looks to be the same tray as the concentrator trays.  This is understandable as you only need the one mold. However if feeding undersize slurry from a sluice I think it would be best to feed into the top water trough so it gets fully spread and smoothed to go to the other trays. This would likely require the higher trough walls as mentioned above.  Although you could feed onto the flat plate but you might get splash over the sides then.

To my mind it is such a shame to loose the potential of the feeder tray to be another collection area. I always like to get it while I can and perhaps the designers found that having that plate smooth and the same angle give the best feed for the G Force separator? Or is just more economical to have one mold for all.

If you watch when you feed it you can see the odd gold flakes hang back for a bit then scoot off to the other trays.  I would like to be able to get a feel for how the run is going without having to shut down and look at the main trays.  A small drop riffle or a little peice of carpet in the middle or near the bottom on the feeder tray should give intant results that you can view and easily clean out. As mentioned this might require a separate mold though.

It would also be nice to be able to re task the feeder tray as a miller table to do the final clean up of the cons from the Gold Cube so it would be an all in one unit. The angle of the feeder tray plate would need to be flattened out or adjustable and you would need to have an adjustable water flow so you have the thin film separation. It is a perfect little unit for this though as it is not too big and already has the water spreader.

I did get a little damage in shipping on the top edge of one of the trays but it does not affect operations and I think that will easily fix with PVC cement - is that correct Mike?

The unit is nicely built and I am happy with my purchase. I also got the stand and like the way it is built. I will be very interested to see what it does with bank run material (screend of coarse).  Need to figure a way to screen my sluice run and limit the water flow feeding to the unit althogh I think there will be quite a wide range that the unit accepts.

Screening to 1/8" really is not that difficult or time consuming for cons. I found an office garbage can with 1/8" holes for 7$ and the dry cons run right through it.  Five gal bucket takes no time at all although can be a little dusty.

Looking forward to more tests and field work.  So far I have been running some othr clean up sluices on the outfall.  But to be fair the feed rate and water slurry consistency hve not been ideal for them so it is not a clear indicator of what the Gold Cube is missing.  Greg in BC

I just recieved my gold cube last week. We also ordered their hand dredge kit, should be here next week. After watching the video's of them getting gold from  lake superior beach sand i had to have this cube and now i cant wait until the snow gets out of here. Although i think i'm going to need a bit more of the hose than was provided with the cube, is this a common hose that i can pick up anywhere?  also Because i'm new at this what is the actual opening size of #8 mesh and so on?

Title: Re: Gold Cube Technology
Post by: JOE S (INDY) on March 09, 2011, 06:45:34 PM
Yes, sir - jerry is right.

A #8 classifer has 8 openings to the inch.  The actual opening is 1/8" minus the diameter of the wire it's made from.  So, if the wire is 1/64" diameter the opening would be 1/8" minus 1/64" --- or --- 7/64" x 7/64"   [-1st-]

A #30 mesh would be 1/30" minus the wire diameter, too.

Pretty easy to see until you get into the insanely small meshes like, say, a #400 or #1000

Glad you got your cube, I have been out using mine for the last week in AZ.  Had a great time and found some real good gold!   The hose that we are using can be found in the lowes and Home Depots here in Oklahoma, otherwise, go to boat supply places as this is a bilge pump hose.  1-1/8" size.  If you get a 1-1/4" just wrap tape around the nipples until it fit snug.  Also, pre-wet the mats when you are ready to use them.  Just turn them over in some water and slap the mats to force water into the deep crevasses, this will eliminate the air bubbles.  Do not use a surfactant in the water.   If you are going to be using it on the beach you may consider using a 12 mesh classifier.  This will eliminate a lot of material and will keep you running cleaner.  8 mesh will do fine though.  If I have to lugg buckets I use 12 if I am close I use 8.

Post by: Greg in BC on March 13, 2011, 10:58:03 AM
Mike, just curious as to why a person should not use a surfactant?  Have you found it negatively affects effictiveness?
Title: Re: Gold Cube Technology
Post by: Okie on March 13, 2011, 12:28:38 PM
All the material is pulled underwater, the gold will never see air again until a clean-up.  If you use a surfactant, you are only creating bubbles and effecting normal flow of water.  The Cube was designed this way to be able to use raw water, a mud puddle if necessary and not risk loosing gold.  When the mats are pre-wet at set-up, there will be no issues with trapped bubbles in the mat, this tip is being added to the instruction booklet.  We have put pulverized ore into the Cube completely dry and have pulled gold out of it.  A second run produced no gold and a panning of the tailings came up empty as well.  So bottom line, pre-wet the mat and no surfactant.

Ok thanks Mike, makes sense. Greg
Title: Re: Gold Cube Technology
Post by: goldmann on March 14, 2011, 10:45:54 PM
Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

I think that means do not use either any type of soap or Jet Dry with the Gold Cube.

MIKE,
Pre-wet the mats by slapping them with your hand underwater.
1) Do the mats-trays have to be turned over upside-down to do this, or not?

1 & 1/4" hose will work if 1 & 1/8" hose is not available.
2) I was told not to use lay-flat hose for a 12 volt bilge pump on another forum because it causes too much drag(performance loss), I still do not know for sure?
BUT I suppose the flexable solid clear plastic type of hose will also work.
 
3) What is the very maximum hose length that can be used with the Gold Cube's stock 1100 GPH bilge pump?

4) What size-type of in-line fuse is to be used with that stock pump?   I gather to use a maximum 5 Amp size in-line fuse, no bigger and only a fast acting type of fuse. Also note that this pump draws 2.5 Amp.

5) Also I suppose the 1" gasoline powered Honda WX-10 (34 usGPM--2040 GPH) water pump would work with the Gold Cube at slow idle(throttle)?

Thank you!
Title: Re: Gold Cube Technology
Post by: Okie on March 15, 2011, 06:21:55 AM
Surfactants or anything with bubbles are not needed with the Gold Cube.  Your gold will not float after the first drop, then it gets stuck and it yours to keep.

Pre-wetting can be done with a squirt bottle as well but without a bottle, it is fastest to turn it upside down or at least on it's side to keep the water draining.

Layflat hose requires pressure to expand.  A bilge pump offers volume at low pressure so a open hose is required.  The maximum length we have used that we noticed material collecting in the trough was 5 feet.  With a 3 foot lift. 

For the fuse application, 2X the amp rating is good so your suggestion of 5 amps will be just fine.  I've never used one but know some of our customers that do.  If the pump was installed under a deck in a boat, I would say definitely use a fuse.  Out in the open right where you are monitoring everything, I say it is less important. 

Your 1" pump idled back should work though I would use a valve to adjust the flow.  Them little monsters put out a lot of water.  Adjust it so the water quits squeezing out all the cracks and you are ready to go.

Thanks for bringing up all these little details for classification.  Happy prospecting!

Mike

Howdee Mike!

Hope all is well with you and your family...  As you are probably aware from the shipping notices, my Gold Cube arrived a few weeks ago.  Unfortunately life was a little too busy for me a little over the past month with work, so my hobby interest in prospecting had to be set aside for a bit. I didn't even get a chance to unbox the Gold Cube until this past week.  For those just catching this post, I purchaseed a Gold Cube in early 2011.  I've just recently taken the Gold Cube out of the shipping box and I have no affiliation with Gold Cube, I am just a recreational prospector who was intrigued with the equipment design and purchased. Although I can foresee resellers distributing Gold Cube kits globally.  My posts in this thread reflect my experiences using the Gold Cube for efficent classifying materials as a novice miner just starting out in the learning curve.  Once I can actually see the ground again, I'll start to include pictures when I use the Gold Cube this season. For now, there is just too much snow.  <-dont~know->

The Gold Cube arrived as a well packaged shipment.  Simple assembly, but I think part of that is because I believe I have watched every video on the Gold Cube, from development and prototypes, through to your current model. I really like the compact design of Gold Cube kit, and the quality material your trays are made out of.  The trays are sturdy, not something that is going to bend or dent, out of the box ready to classify material and take the abuse of the outdoors.  Unpacking the box I thought the support legs/frame that the Gold Cube sits on should have been made out of a thicker material, but once I had the Gold Cube setup; I could see that the frame size was strong and more than adequate for the purpose of leveling the Gold Cube.  Light frame/legs suit the purpose of keeping the overal kit weight down to help with transport to remote locations. 

The frustration of having new mining equipment arrive and there is still four feet of snow on the ground.  I managed to fight the urge to tinker with the Gold Cube for a whole two weeks or so, and then gave in and setup the Gold Cube in the basement, and ordered a bag of pay-dirt shipped to my location.   The very first run of the material was a success, my 4-stack deluxe kit was into production use in minutes.  I had probably 70% in the 1st tray, 20% in the 2nd, and 10% in the 3rd tray.  I ran the material through a 2nd & 3rd time with a few colors showing up in the 2nd, and in the 3rd run I could only find 2 colors. 

If I were to offer anything from my experience with the Gold Cube thus far, that would be; consideration for a little longer pump hose, maybe 10ft? Secondly, I would encourage some sort of instruction set with the package to help new owners 'tweak' their Gold Cube skills for maximum retension of gold.  Even if it was a Gold Cube Tips & Tricks pamphlet included in the kit. Personally, I've taken the time to dig for every piece of info on the Gold Cube (GC) that was on the Internet before purchasing, From all that browsing I think I have picked up a few operational tips in the CGPF - Gold Cube thread and the YouTube videos that have been helpful in tuning the GC's performance. Stressing things like pre-wetting the tray mats to avoid bubble or air pocket issues.  The importance of level operation to avoid material build-ups in the mats on the down slope side of a GC that is unlevel.  Maybe a tid-bit on the physical setup, your recommended and maximum flow rates, no wetting agents, level operations. Even fun facts like the GC could hold up to 5 ounces before requiring the cons to be cleaned out, or using electrical tape wrap to adjust from 1-1/8 to 1-1/4 hose, etc.

Personally I didn't have any problems with the setup of the GC, but I've watched every video and read every thread on the Cube. Whereas my claim partner came over to inspect the new equipment purchased as I was about to run the cons thru a 2nd & 3rd time. My partener didn't know anything about it at all, other than it was some sort of vertical sluice in a box, or such was what he offered as his understanding in buying a GC.  The only area he wasn't sure of during the setup was the recirc. feed pipe section with the loose top plate, but the rest went smoothly. 

We're probably another 4-6 weeks away from being free of snow and soft enough for a shovel to go into the ground. Unless there is a sudden heat wave, as it has been a long winter with record levels of snow.  But once we can get the GC out in the field in late April, I'll post an update on the GC once we can break ground.  Early in the season, I know, plus high waters will still be an issue for most locations.  So far, with the paydirt I've used as a prelimiary test, the cube to live up to expectation of handling a larger volume of cons at a time.  From the very limited time we've had tweaking the GC, I can see that testing different flow rates will tune into efficency of gold retension, from fine, very fine, and flour.  Each batch of cons should be run multiple times, higher flow rate at first, then reduce the flow rate a little, and re-run the cons.  The lower flow rate kept flour gold and specks that were flushed through at the higher flow rate.  Depending on how many buckets of cons one has to process, but I could see pushing all fresh cons through the GC at a higher flow rate.  Then once a few of the buckets in the session have been processed at a higher flow rate, theyn reprocess the bucket cons a 2nd time in the GC at a lower flow rate.  I am looking forward to testing this type approach to processing cons once I can get out in the field with the GC. 

I also look forward to hearing more about your development of some sort of hopper or feeder for the GC.  I've been eagle-eye'in various materials for just that purpose.  It would be nice to be able to have a sturdy crashbox-like feeder. Something that can handle washing muddy clumps of 3" cobbler stone from the shovel. With some sort of  strong spray-wash action above the grizzly that has a gentle slope so the material doesn't fall from the feeder too fast. Not before being well washed, and the grizzly drops thru 1/8" classified cons into the GC (could even handle cons screened to 3/16).  There probably water flow considerations between the grizzly and the GC itself, but those flow rates could be adjusted by valves, and so far it seems that the GC has quite a bit of leahway on the flow rate it can handle and still efficently process cons.

I did run some 1/4" classified material from the pay dirt I've been playing with. For the most part the GC kept up to the increase in size without difficulty.  But I also witnessed why the Gold Cube is specified to process 1/8" or finer cons.  As I did find that one oval shaped piece of 1/4" rock did get wedged in the boil hole going to the 1st tray.  It was 1/4" one way, and about 3/4" on the long edge of the oval.  Processing all the larger (1/4") cons I had at the time, there were about a half dozen larger odd shaped pieces that caught in the mat here and there.   But considering volume of 1/4" classified I ran through it as a quick test, it is hard to base any decision on the results.  Possibly by running the GC for a longer period at 1/4" it may knock loose the material we noticed in a single small volume test.   

I remember also reading in a few different places, that GC owners should be sure to classify down to 1/8" cons. So running the 1/4" cons was testing beyond GC's specifications. In messing around with GC, I did become aware that it important to keep air bubbles off the mat suface for fine(r) gold to fall in the mats. At first I adjusted the flow rate of the water, supecting the flow was too fast for the finer material to fall, and that it was the speed causing white water, which was causing the air bubbles.  When I used the flashlight to get in and see the 1st & 2nd tray surfaces in action, I could see the little bubbles clinging to the mat surfaces. I wasn't using any agent/chem, I just didn't make sure the mats were completely wet the first time I ran the cons in the GC.  Once I made sure all the mats were soaken wet without air clinging on in the crevices, I found that fixed the air bubble issue, and I could actually push a fairly fast flow rate and still capture the very fine 200-400 mesh flour.  The faster flow rates also cleared out more of the black sand. 

** I should also state that all of the GC testing is only based on about 20 pounds of pay-dirt concentrates that I ran through the GC 3 times over two different sessions.  By the 2nd time around, with both of us reviewing the operation of the GC; we were able to tweak the cube quickly.  I can see that with some regular use a person will know what to look for, and what to do if the issue arises. Much like we become with any regular tool we use in prospecting.  Hats off to you guys in designing the GC, so far the cube is living up to all the stated performance markers - and I'm liking it!  ;D

I am biting that the bit for an opportunity to be out classifying some material with the GC in the field.  A few more weeks to wait  <-waiting->   From what I've seen so far, the GC is ready to handle this year's prospecting adventures...

Gambler,

I'm only 15 years behind you, and been doin' it since '66, but .....

99% of all Gold, worldwide - huge nuggets to micron Gold - well I guess that I'd have to say 99%, no.

However ...............................

99% recovery within a certain mix of Gold parameters, and within certain constraints like -#8 classification, and I'd say - Heck Yes.  If not 99% then possibly only 98%.

E Towers have been in use for many years and have been quite successful, in controlled situations, as are used to work the material through the Gold Cube.  Yeah, I think that high a %age is do-able with a modern level of technology and design.

Of course, that's only my thinking.

Post by: k0diak on April 07, 2011, 11:17:38 AM

This past week was my first time use of the Gold Cube running local material collected this during this pre-season melt.  I did the 25gal or so of unclassified material. with a little edge of expanded to stop larger items than 1/8" of an inch going down the first trough.   Not the recommended use of the Cube, but I didn't want to sit there and pre-classify what I had down to the 1/8" screen. The little edge of expanded metal allowed me to make sure all the larger items could be well washed in the top wash plate stream of water and then pulled out clean of stick-on material. I really have to work on my rocker project to do the initial classifying, but this was an over ambitious start to my season with this first run of material.   The cube made quick work of things and had the material concentrated down to about an 1/8th of a cup of black sands and heavies.

The Cube made short work of the material I did have, and in the first tray were the few larger colors, probably between 30 to 60 mesh sized.  Then on the 2nd tray is where the really finer material was collected.   I am really looking forward to the melt completing so I can take it out for a good full day and put the cube through the paces.  But so far, I like what I am seeing.

As for 99% recovery, I think that may vary, but with this small sized first run of the season,  it seemed to live up to that kind of percentage mark.   Time will tell with regular use as to how consistent the retention levels will be.

IMHO, I like the Gold Cube, compact, easily dismantled for clean out, and can operate with a low volume of water as a recirc op.  Does it warrant the price difference between picking up something like a Le Trap Sluice?  That is something that is personal judgment call, for me, yes I think it was.  But at the same time I plan on doing a few le trap and gold cube side-by-side comparisons out in the field this season.

Just getting back off the road, trying to get caught up on the forums. 
99% ??????   WoW I want that one!   Here's the facts as we know them.  We only did one test that we for sure could claim a percentage.  On the shores of Lake Superior Michigan we took 100 pounds of fine black sand and 100 pieces of gold that was smaller than 50 and larger than 200 mesh.  We tested about 18 different prospecting pieces of equipment.  The sand was so heavy that we had to allow over an hour for each piece tested to clear.  After the run we panned and counted each.  The best was 38 pieces of the 100.  The worst was 20.  Then we tried the Gold Cube it ran the 100 pounds in under 6 minutes and retained 98 pieces of gold.  We re-mixed the gold and ran it again in 3 minutes and got the 98 pieces again.  That in my book is 98%.  3 weeks ago we were in Arizona.  We had some real chunky gold.  On that clean-up we had 1/4 oz in the first tray, a penny weight in the second and no gold in the third.  Does that mean I got 100%?  No it does not!  It means I caught all the gold the Cube could catch in the first 2 trays, that's all.  Nothing will catch all the gold.  Some gold is so small you can't see it, you never even know you missed it.  All I can say is Gold Cube will catch more gold faster and more accurately than anything I have ever seen.  Get one for yourself and you will see as well.  You need the right tool for the right job.  Between 8 mesh and 300 Gold Cube is it!  If you are talking micron gold or nuggets, Don't look at the gold cube.  The hardest, most available gold to most miners out there is in the 8-300 range, that is why the Gold Cube came to life.  I guarantee you will miss gold, I also guarantee it will be so little, it will not be worth running the tailings to get it out.  See for yourself, Have a blast!

gambler85 I agree - nothing is 99% efficient that is just stupid propaganda to advertise a product. However, the gold cube concept is valid, and I would like a close look at the manufacturing and actually run some REAL tests, like what Bill the prospector did on his website with the Le Trap highbanker he made. Luckily, there are websites like this and googles and other forums where great prospectors out there do some valid independent testing.

I have worked with the Goldfield Prospector, a $6000 concentrating unit that is well built and sophisticated. I've used it both testing and running concetrates at an operating placer gold mine in the Brooks Range of Alaska. It captured an estimated 98% of the recoverable placer gold, and the seasons total that went through that box was around $700,000, so even 2% of that is sad to be lost. However recovering that last bit of gold would cost so much it would be unreasonable. I was re-running all the tailings already, so the final tails were crap full of black sands which are impossible to process economically at some point.

My point is that I havn't seen a thorough independt test published by Gold Cube, and until they or other companies begin doing that, I don't believe any crap written on their website, or editted in their videos. Still, lots of Brazilians miners use the concept of short sluice boxes piled on top of one another, and I love the idea of very quick cleanups. But for now I'm still partial to the typical sluice box design and not gizmos that are very expensive considering the cheap materials they're manufactured from.....

We should start seeing homemade Gold Cubes soon....

Now you are the one making judgements and claims against the Gold Cube without any proof, your the pot calling the kettle black. There was already feedback and tests on the Gold Cube on other forums, many were positive with some pleased owners. The Gold Cube is not designed for individually invisible micron gold under 300 mesh, but instead for visible gold. It is good machine to clean-up for a larger operation.

Thanks Goldman for the step in.  You will see that all that he says is true and all his concerns, though a bit rough, are genuine.  The day will come that dylan.e.mcfarlane will have the proof he needs with this machine as well as any other machine he has ever tried.  I really hope everyone gets a chance to see it first hand.  There are quite a few new owners out there from small to large scale miners.  Ask around, there may be one closer than you think.  Meanwhile, stay skeptical, but trust me long enough to give it a fair try.  This machine was invented to help the industry.  Actually it was designed to help me!  We just chose to share it.  We appreciate any honest feedback.

My two cents worth...I am currently using the Gold Cube to clean concentrates from my dredging operation.  I have the 4 stack unit which has three trays.  Once the rainy season starts and the river gets dirty (I am in Cambodia so that could be anytime between now and July), I will do more of a "scientific" test, but I will report my "observations" to you now.

A. The Gold Cube appears to live up to the claims its makers claim.  I can not report on the actual percentage of recovery yet as I haven't performed my "scientific" test yet, but visually I would say it is true or pretty darn close.

B. The gold we are getting is ALL minus 30 mesh with about 20 percent minus 30 plus 40; 40 percent minus 40 plus 60; and the balance minus 60...so pretty small stuff.

C. Of the gold the Cube is recovering for us, probably about 85 percent is on tray one; and 15 percent on tray two.  Rarely do we see any gold on tray three.

D. We have panned MANY buckets of "tails" with only the occasional pieces of gold found, so no it does not get 100 percent.

E. The feed rate is pretty good.  We feed a 5 gallon bucket in about 10 minutes and it appears we could feed a LOT faster, I just don't like to feed cons so fast.

F. Though some people have commented on how expensive the Gold Cube is, I can only guess that you have never been involved in manufacture/retail before.  There are a lot of costs that are factored in to a retail price.  The cost of R&D, molds, and other expenses need to be amortized into the price based on an expected product sales lifetime or "How many of these darn things will I sell."  Let's face it, Gold Cubes will never sell as many units as an iPod so the amortization of expenses cost will be higher.  The components such as bilge pump, hose, steel frame (nicely done by the way), are priced very much in line with other mining market items.  The Vortex matting is EXPENSIVE as I have found it available on the internet already from a couple of different sources. So, when you add it all up, the Gold Cube is a reasonable value.

G. I used to own Armadillo Mining Shop, but no longer sell any mining equipment...including the Gold Cube, so my observations are not self serving as I am not making any money from increased sales of this device.  Is it perfect, no.  Can some extra features be added , yes.  Would I recommend it to my best friend to buy one, all ready have!

She's as stoked as I am!

Ordered my GC last Wednesday got it on Friday.  ;D  I got the 4 tray version.  Thanks Mike for the fast shipping. {cool^sign}  Got it unpackaged and put it together. The only thing that I would change on it is the pump hose.  Why? Because it is to short for the 4 stack version and the GC discharge is directly under the hose inlet.  Dont want to suck up my discharge.  So order an extra 2 ft of hose on the 4 stack version an you will be able to run the pump out of the way.  If you do the 3 stack version then the hose is fine as is, if it is the same length.

I havent got to run my setup yet as I am building a self contained recir unit.  I hope to have every thing finished by this weekend if the rain permits.  Will let everone know how she does.

Post by: Okie on May 26, 2011, 06:29:24 AM
Glad to hear you received the Cube Mike.  There has been some talk about the hose length.  I use and demonstrate with 3 feet of hose.  With a longer hose you will start to reduce the amount of water.  The more water you have the better the Cube works.  There was one guy that wanted to set his over a 5 gallon bucket so of course his hose was too short to reach the water.  I use a black tub and a 12x14x6 deep tray just under the discharge to catch all the tailings.  As this fills I pull it out and dump out the large waste.  Any silt that gets by won't hurt the pump, all the tails that could clog the pump get removed.  Another thing folks are attempting is to put a stocking over the pump.  That trick is not to protect the pump, it's to keep spray bars unclogged.  The Gold Cube does not have spray bars.  Don't restrict the flow.  Step away from the panty hose.

Sure hope you get out to use the Cube soon so you will show some pictures.  It is pretty funny, the most pictures that I see are the ones that the new owners have gone through their old barren buckets and find out they were not so barren.  Even had one guy mad at me because he scraped up some material from his driveway where he dumps his old material.  He found a bunch of gold and was mad because now he has to re-work the whole driveway.  Think of all the gas he is saving and how close the refrigerator is for him.  I think he was pretty impressed all the same. 

Enjoy the cube, Go get some yella

Just curious ... How much water can I push thru this?  I built a small bilge pump stand for my 2200gph unit that I could use.  I just dont see 2200gph flowing out of the 3/4" pipe.  So what are my ranges for water flow?

As far as Panty Hose.....  I love the stuff ;D  I use to keep a bunch in my tool box.  I found out one day out in the middle of know where that my power steering pump on my mustang froze up and broke the belt.  Bad part about it was that belt also drove the water pump.  Thought I was stuck, but and old timer told me about panty hose.  Thought he was nuts but I had nothing to lose.  Walked in the store and bought some, rolled it into a cord, wrapped it around the drive pulley and the water pump pulley and cut the ends off.  Well lo and behold it worked!  It's better if you burn the ends off but still.  I drove that car for a long time with panty hose for my belting.

Water flow, between 800 and 1800 is the range.  The 1100 with 3 feet of hose will barely crest 800 gph You could use the 2200 with a valve to dial it down.  Run it with enough water flow to flood the buffer plate top.  Then turn it up until it starts to over flow the buffer plate and make a mess.  At that point you have reached max.  A longer hose will work to your advantage in that set-up.  Have fun!

        One thing that I've noticed about most of these "Gold getting" gadgets is that none of them actually prove that it did recover 95% of the gold by completely panning out the tailings at the end of the test. It's true that it would take another several hours to do such a proof, but for the sake of argument it would have been the final kick towards a sale. Just my 2 cents worth.

The main inspiration and design was plotted in my little head and all the prototyping and field testing was done by my partner Red.  I had it on the beaches of Oregon this march and it did really well.  Though I still think the beach of Lake Superior has the most difficult gold to process.  I even ran some material from Nome through it in the testing stages and it had no trouble with them either.  There are 4 that I know of that will be setting up on the Nome beaches this season so I will have to wait for the reports from them.  Thanks for taking the time to read the entire thread.  Knowledge is power.

SWEEEEET!!!  The wait was killing me, I bet it had you chomping!  Do you have any fingernails left?    Remember, there is a slight film on the mats, scrub them off, This batch of mat material had more release agent than the first batch.  Clean it off with some dish soap and you are done.  Now when you run it, pre-wet the mat so there are no trapped bubbles but never use a surfactant again.  It is all in the instruction manual.  We need pictures okay?  Go git sum Gold and snap some pics.  Woo Hoo!!!

Okie-

 "but never use a surfactant again"

Mike over here in Cambodia.  The water here has such a high surface tension, if we don't at least use dish soap the losses to floating gold are unbelieveable.  Does the Cube not work optimally with surfacants, or do you think they just aren't needed?  We RARELY see gold on the third tray, so it seems to be working well for us.
Title: Re: Gold Cube Technology
Post by: Okie on June 03, 2011, 08:46:30 PM
HI Mike
All the material is drug under water on it's way through the trough.  Even if you had an oil slick and sun baked material, It would be drug under the water and away from surface tension.  Your gold will never see surface again until you do a clean-up.  At that time it is well controlled in a pan and you can add a surfactant to pan it out.  When I demonstrate or use it in the field, I never have to fight with the bubbles.  When I do a clean-up though the water is hard and raw and the gold floats as quick as it has a chance to dry a second and and get stuck on surface tension.  There were 2 conditions we addressed when creating the Gold Cube.  One was water straight out of the river or mud puddle or where ever and another was bone dry desert material.  The G-Force separator trough took care of those 2 concerns, so, no bubbles are required.  That also makes for a strong point for the eco-nazis who would jump on the chance to say we are polluting.  No bubbles no troubles

Mike

Looks interesting ... but if you look at the sand they are using in their demo; it contains virtually no clay ... in the real world where quality Gold bearing river sand resides near bedrock, there's often a certain amount of clay to contend with ... I think the "trough" area of the Gold Cube may face "plugging" issues (even if the sand is classified to 8-) if being fed with sand that contains a certain minimum amount of clay ... one way around a clay-plugging effect might be to thoroughly liquify your concentrates/slurry in a bucket before adding to the Gold Cubes' slick plate... hopefully they've done some R&D with clay'ish sand and have some solutions.
Title: Re: Gold Cube Technology
Post by: Okie on July 31, 2011, 08:09:29 AM
Welcome to the forum Trueluncher
In the video, our goal was quantity and then the second run of the same material to show it's recovery.  The two things accomplished were, you can feed the Gold Cube pretty darned fast. Second, though you will loose gold with every machine on the market, there is no practical reason to run 1000 pounds of material again for a nickel's worth of gold.  Go get some more new material and get more gold!   In the video there wasn't much clay at all.  Your suggestion to liquify clay before adding it to the Gold Cube is something that we do when we are actually scraping the clay layers to pull out some pretty good gold.  As you can see in the video, we allow all the tailings to collect in a removable tub, if you are in a clay area and feel like there is a significant amount of 1/8" clay balls that are making it out of the Cube that contain gold, you can just re-run the catch tray material until you are satisfied that the clay is dissolved and all the gold is released.  If you are in an area that contains clay but not really a clay layer, 1/8" classification will break it up and the action of the Gold Cube will finish it off.  The flatter the gold or the more clay you are in, the farther down the Cube you will find the gold.  If you gold is all free from the material, you will find 90% of the gold collected during the clean-up will be in the first 3" of the very first collection tray.  As far as you concern about material collecting in the trough, If you classified your material and water flow is correct, you will not get a plug-up in the through.  The only thing that will stay in the trough are heavy rocks like magnetite that are close to the 1/8 size and some pickers.  That's always fun to see when you take off the water tray and see shiney eyes looking back at you out of the trough.   I don't know of a Gold Cube in your country yet.  We will be adding more videos to the website so stay tuned for those.  Have a great day!

Mike

Bob that is pretty interesting. There was some coarse gold found on the Charlottes at one time. You ever check any of the creeks out?

 Ya this is interesting country here. Some of the ground east of Oweekino kind of above the lake looks interesting placer wise but I will never go in there. Be far too expensive for me. If I was 30 years old though I would sure go in there.

Hey did you ever work with or for Norm Jones?

Basically I have 2 thoughts in mind for the Gold Cube. I really dislike panning so concentrating my concentrate and tailings from high banker.

I guess there is no Canadian dealer for Gold Cube. <grin>

We`ve checked out a few creeks here and found a bit of colour but nothing to brag about. My real obsession is the fine gold found in the black sand deposits of the east coast of these islands.These deposits are VERY rich but the gold is so fine it has driven many placer miners to distraction trying to separate it. I`m hoping the Gold Cube is the answer and, from all reports, it is designed for precisely this kind of application.
I never logged for Norm Jones but I`ve heard the name before. I logged for an old gyppo by the name of Frank Gildersleeve. You`ve probably heard the name before as his family logged on the Coast for a few generations. They made their fortunes in the days when the Coast was logged with big skyline yarders on A-frame rafts and the bunkhouses were all on floats. When men were men and sheep were shy  <-laugh->
I`m not much of a fan of panning either; especially considering the ultrafine flaky gold I`m dealing with. I`m very interested in the work being done by a guy on here that goes by the handle Willthedancer. He has developed a compact centrifuge that looks very promising although slightly out of my price range at the moment.
Anyways, Will is quite the experimenter and he posted some of his work on microwave gold smelting a couple of weeks back. He claims to have had good results with this technique. The beauty of smelting is that every minute particle of gold is captured and put into a button.
Not sure I recall the name of the post but check it out if you can find it.

Bob, I have heard the name Gildersleeve. Never met him. My neice married aguy who is in his 50's now was born on one of those floating shows. Logged all his life. Can't remember his last name at the moment.

I saw the microwave post. Its pretty interesting stuff but too scarey for me. I used to blacksmith knives and I had a clay crucible made for me for melting inside my propane fired forge. Borax and heat. I think wood ashes would work for the flux as well or even some of the clay from the claim.

I have seen gold like you are after. The stream carrying your tailings out of the box sparkles on a sunny day.

It definitely sounds like a Gold Cube would be right up your alley. I will look around for willthedancers concentrator, I had not run into it yet but I think I will be going with a gold cube. But I can wait and see what the reports from guys who bought them sound like.

Sounds like the Gold Cube would be a real good fit for type of gold your after! I'm after reeallly fine stuff out here mixed with real heavy clay soils, so a bit of tweaking following Mike's suggestions of multiple tubs to help settle all the suspended solids, the use of a flocculant (pool clarifier) to drop those solids to the bottom of the tub quicker, or running clean water exclusively helped a great deal. I still haven't mod'ed my high-banker pump and 1/8" hopper/classifier to the Gold Cube yet.., :-[..., I'm running the high-banker steady these days exposing a rusty gravel layer trying to define the zone. (Lots of material needs to be moved) I'm running the high-banker pretty flat to catch as much of the small stuff as I can, I even have my Keene folding sluice set up behind the high-banker to catch anything that is still suspended after ejection from the high-banker. Once the paystreak is defined I'll work it with the 'FrankenCube'!! (then I'll know for sure the amounts that got away with high-banker!) nerd$#@

After researching all the various prospecting forums out there for user reviews of the gold cube, I finally decided to get one myself (actually for the company I work for in Alaska). We are starting a large placer drilling project in Nome, AK (on the historical deposit which was dredged by USSRM). Although we are using Goldfield Prospectors and an iCon Falcon to process the drill samples, I plan to experiment with the Gold Cube, and probably use it to test our pan tails and sluice tails to ensure we're not losing any gold on our real testing equipment.

Add a flow regulator to it.
It will come with a 1100 GPH pump but we often tone that down 5 - 15% depending on the material we are running.
Do NOT take it too low however.

It will come with a 1100 GPH pump but we often tone that down 5 - 15% depending on the material we are running.
Do NOT take it too low however.
I gather that is with the three(3) feet of 1-1/8" hose that comes with the GC you are talking about.??

Also if you go to more hose length, the GPH drops down low that way too.

We don't use the small hose length it comes with. We use a slightly longer hose but still use a regulator at times.
If we are running large amounts of concentrates from highbanker through it, then we'll tone it down just a bit. Not much.
This is after we classify them.

Hello everyone and thanks for looking at the Gold Cube.  My Partner an I have been working on this device for some time now.  This summer we struck gold, so to say, with this design.  Reading some of the posts to this point has found me impressed with the knowledge base.  Let me start with a little background and then I will answer some of the questions the back ground didn't cover.

In July 2009 I was on the hunt for some beach gold on Lake Superior Michigan.  Well I found some and asked the rangers there if I could set up a power sluice to capture some.  They said it was fine but later found out I needed a permit.  I got one and went back a couple months later.  See here's how I did.  [nofollow]http://www.youtube.com/watch?v=f3ry5gHaHtA[/nofollow] Meanwhile, After finding out how difficult it was to retain very flat gold in 90% black sand, I contacted as many groups as I could to see if there was a trick to this stuff.   A couple of the groups actually led me to the information Trev had accumulated and posted.  It was great reading.  I contacted his lawyer buddy in Texas to see what the boundaries were if I came up with a device that incorporated the columning effect caused by the gated trough.  The trough idea could not be patented but the unit design could.  Looking at the pictures, we knew there needed to be some size reduction and the zig-zag design was it.  This accomplished two things.  It keeps things compact and it forces more water through the trough at a higher pressure to keep everything moving, even clay ridden material.   That being said, we also needed to find a suitable mat.  We found some incline conveyor belt that was perfect.  Since the flow in this unit is so fast, this mat had everything we needed for retention as well as being able to keep itself flushed of debris.  After quit a few prototypes and a few thousand dollars, manufacturing and patenting the design is underway.  This thing will be mule kick proof and easy to carry.   It is a recirculatable unit that will need water pumped into it.

There is a correct tool for every job.  This is not an off the bank type unit.  Everything has to be classified down to 8 minus.  Most of the gold in the world that can be seen falls into this category.   This is also where it gets tough to process.  The Gold Cube shines at the end of a day or at the end of a trip when you have many buckets of concentrates.  What will you use to get out your gold?  A Wheel?  A Bowl?  Water table?  A Pan?  If you have been working your favorite spot for a while with your dredge or power sluice, you may just have 10 or 20 buckets of concentrates.  I just picture this pile of buckets and standing there with a spoon at the ready to start feeding your machine of choice.  "I know, I'll just save it for winter!"  Now all you have to do is classify to minus 8 and run it through the Gold Cube.  Everything in that pile of buckets will be reduced to about a cup of material and now you can use your spoon with a smile.  All the larger stuff is an easy pan.  Even better, if you have a gold metal detector,  it should easily find gold 1/8" and bigger.  Just spread it out and pick up your pickers and nuggets.  So what are we missing here?  Hauling a ton of concentrates back with you, that's what.  Oh happy day!  Better mileage and more room for the dog.  

In the video on the site, There was a bit of clay but the act of classifying really broke things up.  It took us about 2 hours to fill the 16 bucket.  We classified with the bucket underwater to the rim so the material was washed pretty good.  All the concentrated material in a dredge or power sluice is washed pretty good as well.  You will also notice in the video that we were really pouring the steam to it.  We were racing the clock.   We really wanted this to fail or clog up, neither of which were achieved.  But we did complete in about an hour, I think it was actually 68 minutes.  It just kept clean and wanting more.  Earlier, we had even tried to get it to fail with 7 gallons of pure black sand in 10 minutes.  It just kept eating it!  On a side note though, the black sand was contaminated with 1/2g of gold, bummer!  The guy who brought it to us was sure he had gotten all the gold out.  We ran it again to make sure and discovered we missed 2 specks.  Truly not worth the effort of running again or saving.  

(Bill) I know this may invite more questions but we have done extensive R&D in many gold situations including Nome beach gold, Oklahoma red clay, drywash concentrates from NM, AZ and CA.  5 different locations in Colorado, and every type of material we could get our hands on.  If you have something you can't get the gold out of, I would love to try it, I'll send you back the gold.  So far the Gold Cube has not failed.  The worst that it did was back in Lake Superior, the hardest gold in the world to recover!!!  We solved the problem by adding 2 more layers.  It took our retention rate from 70% to 98%.  How did we know that?  100 pieces of gold counted and ran.  Then we counted the clean-up.  We needed to know for sure!  We have a lot of time and money in this thing.  Blood sweat tears and love and guts.  This will fill the part of the mining that has always been an issue.  The part between a pile of concentrates and you being able to see your gold.  Quick reduction without a lot of time and an acceptable minimum loss.  Such a small loss you will not be tempted to run it again or save it to run chemicals.  I have panned the Gold Cube super concentrates down to a 400 mesh.  and know it will hold them.  At the end of the video we state that we will run them again.  That is part two.  I panned the second run down to 400 as well and couldn't see any.  There were a couple 200, 100, and 50 mesh though.  About 1% as much as the first run.  It will be shown on the next video.

(Jerry)The slick plate does act like slate, When you dump the material in you can see the stratification.  It is a lot of fun to see the gold lagging behind.  Then down it goes.  Just a quick indication that, Yes, There is gold in this batch.

(GollyMrScience) As your assumption, yes there was more time involved than just the hour.  But as you have read, this is not intended to be the sole prospecting piece of equipment although it could.  The Gold Cube is intended to super concentrate after a dredge or power sluice etc.  That is where it will excel!  It is wise to point out material preparation as part of the time a miner spends but the bottom line is, when you grab a shovel and pick, it's work.  Whatever machine you run it through you will be left with the good stuff.  Your gold is in there somewhere.  If you are a hard worker or if you have a lot of help, you are going to have a lot concentrates.  typically at a ratio of 40:1  the more you move the more you get.  Our experiment on tape was about volume.  The gold was a nice bonus.  Man! could you imagine if we had been dredging and had all those bucket?  Whew!!!!!!!!  I need to sit down!!  Thanks for your factual mind.

(Deserdog)  Yes, this is a forced version of the same principle Trev shared with us.  Them old miners were smart, we are smart to learn from them.

(Lonetree) I'll put your name on one.

Please feel free to contact me.  I'll answer any questions.  I'm really proud of what has been accomplished an you guys are a jury of my peers.  I thank you for that.

We have had our 4 tray unit for some time now. It is great for fine gold, or running your concentrates through once you've classified them down to smalls. We also ran some tests on adding it to the end of our highbanker. Ran a -8 screen under the the tailings and let those run through the cube. Took a while to come up with a way to control the flow, but finally got it to work.  {-applause-}

Hey guys, check out this new gadget coming out at the end of November:

[nofollow=http://www.goldcube.net]Gold Cube[/nofollow]

It concentrates a thousand pounds of dirt down to about a pound of superconcentrates with less than 1% loss of gold.  I don't know yet how much it's going to cost; have an email inquiry in to them now.   Make sure you check out how it works; pretty fascinating stuff.
looks like a real fast way to process beach sands!

Yes, there are a number of things to do with a Cube.

Re-run undersized concentrates from a larger operation.

Run Beach sands.

Run or re-run dredge concentrates.

Run or re-run shaker concentrates.

Run or re-run trommel concentrates.

As well as others, too.

Yea, they are still greenhorns even after almost 2 seasons. They should really be sampling the last foot of the box to see if gold is slipping down that far, and if so adjusting the setup, but nobody thinks about that.

Yes they are blowing fine gold out of there like crazy but the real pitty is that the cost to go and get what they lost will likely not be economic but if they had saved it would have been the difference between making it or not.
Just imagine running material and barely covering your costs per yard to run and then add 5 more dollars to each yard. All the cost to get it to the plant are covered all the operating costs are already there - just add a teeny bit more gold and you have a viable operation.

Sounds like a pretty good tri-fecta!  I'd swap the wheel for a bowl though.  Even better, I would hone your panning skills.  After the Gold Cube, there will only be 1-1/2 cupd of material to pull your gold out of.  Not a tough feat.  Now go out there and find that gold!!!!

Title: Re: Gold Cube Technology
Post by: Okie on January 30, 2012, 12:57:43 PM
Welcome to the forum rafaelro
There are two different processes these two machines accomplish.  The wave table will bring you down to clean gold and depending on the material preparation, your expected gold size recovery will vary.  The amount of material is usually fairly low with a wave table as well unless you get a very large expensive one to handle greater volumes. 
The Gold Cube is a super concentrator.  It will not clean your gold.  There is always going to be 1-1/2 cups of material in a clean-up and therefore other material besides gold will be there as well.  The Gold Cube will handle up to 1000 pounds of material per hour and is capable of holding many ounces of gold before you have to do a clean-up.  Then you should use your gold cleaning device of choice to remove the gold from the garbage.  In your case I see you may be leaning towards a wave table.    The bottom line though with any operation is volume.  How much material do you have and how long do you have to get it all processed?  Hope this helps your focus.

Mike

Gold cube for sure...................
I own the 4 stack, nothing to break, easy to use.
No parts to replace and where you'll be that's important.
Let them pan into tubs of water.
Then take what they panned out in the tub, screen it to 1/8 and run.
That will get larger gold out first and let them see what they miss.

Title: Re: Gold Cube Technology
Post by: Okie on January 30, 2012, 06:11:05 PM
When I classify to 1/8" or 8 mesh, I take all the oversize material and scan it.  I use a metal detector and a plastic scoop.  One scoop at a time I wave the material over a stationary coil and if it sounds off, I pan it.  If it stays quiet, I toss it out. 

Mike

Title: Re: Gold Cube Technology
Post by: rafaelro on January 30, 2012, 06:34:01 PM


yea that sound good to, but to work perfect you need to find a metal detector that discovery gold as small as 8 mesh  i dont know if it exist or not becuase i dont know nothing about metal detectors.thanks
Title: Re: Gold Cube Technology
Post by: Okie on January 30, 2012, 08:30:52 PM
All detectors that are rated for gold can easily sound off on a piece of gold that is 1/8" and larger.  They all can do that since there is only an inch of scoop depth they need to penetrate.  It's a very quick way to make sure your larger gold is not being tossed.

I guess you could just have a small bucket just for "hot" scoops.  After a while they could just be run through a small sluice to zero in on the +8 Gold.

Thanks for watching the Video oldwise1.  Everything that we ran was 1/8" or 8 mesh and under.  I think you will agree that this is the size that is difficult to pull gold out of at a rate greater than spoon feeding.  We feed at up to 1000 pounds per hour so we use a dang big spoon.  AKA scoop.  For prices have a look at our site (http://goldcube.net).  Have a sit-down and read all the information that has been presented in the thread to date.  Enjoy

I watched the video, and my first thought was that they were only using sand. Anything much larger would without a doubt jam or plug it up. Neat little unit otherwise. I am waiting for the price too. <-good_>

As long as you screen to 1/8" you can run anything through it.
Sand
Dirt
clay
rocks
mashed potatoes............
It will catch all the gold. Our testing puts it in the 99.6% - 100% on catching gold to -100 on all the runs we have done.

Just remember, this is a super concentrator, not a sluice.  Read the directions and you will note it says to classify to 1/8 BEFORE you run anything through.

Hey guys, check out this new gadget coming out at the end of November:



It concentrates a thousand pounds of dirt down to about a pound of superconcentrates with less than 1% loss of gold.  I don't know yet how much it's going to cost; have an email inquiry in to them now.   Make sure you check out how it works; pretty fascinating stuff.

Looks interesting ... but if you look at the sand they are using in their demo; it contains virtually no clay ... in the real world where quality Gold bearing river sand resides near bedrock, there's often a certain amount of clay to contend with ... I think the "trough" area of the Gold Cube may face "plugging" issues (even if the sand is classified to 8-) if being fed with sand that contains a certain minimum amount of clay ... one way around a clay-plugging effect might be to thoroughly liquify your concentrates/slurry in a bucket before adding to the Gold Cubes' slick plate... hopefully they've done some R&D with clay'ish sand and have some solutions.

I'm just calling it the way it see it,,,I see in this video that they say 16-buckets and or 1000 lbs of material that they ran thru this ((((What system)))...And put it all in this little blue tub...I wish I could say that this video was funny but it is not...But they will put all the gold in those buckets and put it right there in that little blue tub....HERE WE GO!!!!    AND     HERE WE GO!!!!...
I'm hope this is spam or a joke,,,,I'm going with the thought of both spam and joke... <-yahoo_>

I see this settup is running a (((RECICULATING PUMP))) don't look to big on the pump to me---or at least in this video....

I think it would be real hard on a reciculating pump to handle 1000 lbs of material with 5-gals of water but what do I know...

Even if this system could hold 110-gals of water which is --2--55/gal DRUMS....And do a 1000 lbs of (((what he does not say))) what it is,,,could be dog poop for all I know..

I just know with a 1000 lbs of material I could build a big SAND CASTLE ON THE BEACH...And I dont see any kids with spoon and buckets building anything...

Oldwize1:

Just go to the link for Gold Cube and check the basic price.  They advertise here (and you can click their link) or just go to:

 Gold Cube Home  (http://www.goldcube.net/) 

The 'Basic 3 stack' includes one 'slick plate' tray, two separator trays, a short hose and the threaded hose to tray adapter.  The price is shown without shipping and going to the phone to them should let you know what the shipping costs are. {cool^sign}

DoradoD:

I plan to test a 15 - 20' high pile of old trommel undersize tailings with my G-1 and / or Gold Cube this spring.  No telling what will happen there.   [!!DANCE!!] :o

The 'Cube' can be used as a recirculator - so, depending on the character of the tailings, the specifics of the recirculating system, the relative humidity, the sunlight, the wind and all the other conceivable variables yes or no is hard to decide.  I guess you’ll just have to try it  <-yahoo_> and make a full report soon.   <-idea->

Not really - specific gravity issue. If you used half the water flow you might be able to trap the silver and black sands - silver is around 10.5 and the black sands are probably around 5-9 depending on what they are.

So maybe I am wrong, but seems it would be hard to get enough water flow to clear the heavies yet keep the silver - I see a lot of silver in my area but ignore it mostly...

Here I am.  The Gold Cube is not designed for silver but could work with better classifying and magnetic removal.   Also if you are trying to get the silver, you will need to slow down, about 200 pounds per hour.  Classification needs to be in 8-20-70 mesh batches.  Otherwise the garbage will out weigh the silver. 
Specific Gravity of common materials
Sand --> 1.9 to 2.5
Diamonds --> 2.26 to 3
Magnetite --> 4.7 to 5.2
Hematite -->  5.4
Silver --> 10.46
Gold -->  19.28

So you can see the greater advantage you can give the Cube the better it will perform in the middle regions. 

Sorry for the delay, I'll be at the shop for the next 2 weeks, answers will be faster.

I love the thing but my neighbors hate it when they catch me in their spare gravel ;).

Getting 8 mesh with classifiers is a pain in the ass because the gold cube just eat's it way to fast... I had to build a custom classifier to move enough material to keep the gold cube happy.

Hi Mesojdm...
The Gold Cube runs at 1100 GPH and the surface area is 12" wide.
Therefore there is not enough energy / velocity to make the mats active.
It's best to leave the unit alone and use it as it comes out of the box.
We have run test, after test, after test... on the Gold Cube and it is by far one of the best concentrators "out of the box" on the market.

Mesojdm,

After capturing 1.5 dwt of Gold on that 4th tray the answer is yes. 

Will you capture that amount of Gold, specific to your area, in a week or two, or three, or four?

Only you can answer that.

Joe 

Title: Re: Gold Cube Technology
Post by: Okie on April 10, 2012, 09:42:18 AM
The answer to the 3 or 4 stack question is really based on the shape of your gold.  3 dimensional gold will fall out faster and never make it to the 4th tray. 3 would be just fine.   Hammered flat gold will "kite" or flip in the water making it cover more ground.  This is where you need more trays so the 4th is essential for this type of gold.  Sometimes it could just be gold fever and you feed it too fast.  If you go faster than 1000 pounds per hour you could force gold to travel farther to find a place to get caught.  Hope this helps

Post by: Sir Pans Alot on April 21, 2012, 04:41:33 PM
I have been using it as my primary and it catches gold. Only problem for me is when I go out by myself I need to classify first, then feed the cube. The cube eats dirt faster then I can classify(even with custom classifier). Defiantly a 2 or 3 man job if you want to keep it running dirt.

If it easy to carry around with the battery back and if you don't want to get a high banker, then this is defiantly excellent for primary.

(Fraser river and lower BC is where I usually use it.)

After testing the Lake Superior Black sands on the same beach I found the gold cube is flawed and will not catch anymore micro gold then any other sluice set. In fact the micro gold it will catch will also be loaded with black sands.
Anyone can catch flour gold for far less money just by using the back side of any v-matting running without riffles in a self contained recycling process, in fact the back side of the v-matting will catch flour gold the size of a needle point, but the only way to process the micro gold and get all that black sand out is with a miller  table. If your gold is larger then flour gold and you want to wash out the black sands a section of corrugated pipe will do or even the Le Trap sluice or you could even set up two gutter run off trays with the steps for under $30.00 and do the same thing the cube does for a lot less money. 
Title: Re: Gold Cube Technology
Post by: Okie on April 30, 2012, 07:43:00 PM
Hello William
As you may have read in this thread, the Gold Cube is a super concentrator, not a gold clean-up device.  You are going to have about a 1/2 cup per tray of super-concentrates to pull your gold out of.  This is way better than the bazillion buckets you started with, but no where near ready for the vial.  The Gold Cube was designed on the beach gold of Lake Superior, the black sand there is extremely heavy and the gold is small and hammered flat.  The three biggest mistakes that will cause gold loss in the Gold Cube are 1. over feeding  2. too little water.   and 3. Bubbles in the Vortex mat.  Also with all fine gold recovery you need to classify more if you are expecting to get smaller gold.  An 1/8" bolder of junk will knock out a 200 mesh piece of gold.  Classify to 100, run the plus in one batch and the minus in another.  A little more work and a lot more gold.  The Gold on your beach is not forgiving at all.  When run correctly the Gold Cube will catch that Lake Superior gold.  It's where we started.

Start with panning and learn to pan. GC are specialized recovery devices. If you make the jump to equipment without doing an apprenticeship with a pan, you will handicap yourself severely.

With a pan, you can learn to process material fast (<5 minutes a pan) and down to about 250 micron fairly easily. This apprenticeship will take several weeks to a few months if you keep at it almost every day. You will be mobile. By this I mean you can pick up and move to a different spot to pan sample. By pan sampling you can learn far more about where the gold is concentrated in enough quantity to work or not work.

When folks set up equipment, they tend to stick where they set up just because of the hassle of moving it and resetting up. Imagine doing this 10-20 times a day. With just a pan, no problem.

Admittedly, most folks make the jump far to early in this adventure. I did and then I went back to panning because of a combination of no disposable income and lack of equipment because the move to Alaska meant leaving stuff behind in Oregon.

Now, I always pan sample to determine whether or not to haul in equipment. The determination is based upon size and concentration of the small deposits. Many are small enough to clean out in a few hours. The gold hereabouts is flour gold and is concentrated on skim bars almost exclusively.

With lots of experience panning, you can do a pan every 2-3 minutes and down to 150 microns before it gets difficult. Panning is the standard for testing equipment recovery.

Now, does the GC work? Probably. Do I own one? Nope and I don't see it as the solution to any problem. Is it really fast? Not if you have to classify first. These opinions are based upon several decades of experience. But I'm still learning. My opinions are known to change with new and/or better information that I can test for myself.

Find a club to join. Having a mentor and a gold-bearing location to learn at helps a lot. Good luck. I'm rooting for you.

Post by: gollum on May 07, 2012, 05:11:34 AM
OTE - I wish that I had read your post earlier on. I bought a GC and a Blue Bowl early on and relied upon them for my primary prospecting. My reasoning was based on the characterization of my find. I am working an alluvial deposit that is approx. 15 foot thick down to bedrock. The first 18 inches is a small gravel deposit with up to 1 inch rocks included. It requires a lot of work to remove all organics, clay and small rocks. Lots of classifying. From 18 inches to approx 48 inches is sorted sand that for the gold cube does not require classifying. I find gold in both of these layers but not as much as the next layer. From 4 feet to approx 15 feet the sand includes large cobbles and lots of gravel. I find a lot of flour gold attached to the cobbles and I have to wash them thoroughly to get this gold.
I use the gold cube on the middle layer and because there is no water in this dry river bed I haul the cons home in 5 gallon buckets and use my cube to concentrate. I use it in recirculating mode with an overflow system and I can run about six 5 gallon buckets through without changing the water. Then with new water I run all of my tailings through again. The second run I will get about half of the concentrate I got the first time. I used to then run my cons through my Blue Bowl which took forever and try to seperate my gold from the heavies. I happened to meet a visitor to my area and he showed me how to pan and I bought two gold pans. Now I pan all of my cons straight out of the cube and have learned how to recover the gold out of my pan. It has saved me lots of work and I can recover the gold from my cube concentrates in a fraction of the time it used to take. In summary I love my cube but I should have followed your advice and learned how to pan first.
Thanks for sharing your time and experience with us  "noobs". bill

Post by: williamsingr on May 07, 2012, 06:17:37 AM
 Im sure it will catch a lot of gold however the gold on that beach is mainly microbial and without a miller table your not going to get that gold out. You could clean up your matts all day long and end of with a lot of 5 gallon buckets full of black sand and micro gold and still need a miller table.   What I was trying to achieve was catching gold without retaining high concentrations of black sands. I was expecting small flakes of gold but the flakes I found where all pin sized and smaller, smaller then I was expecting, I dumped my riffles and flipped my matts over . By using the back side of the V-matting and no riffles the gold was sticking to the matt with every feed and washing out the black sands. I even took out the vortex matting and found I didnt lose any gold other then the micro gold, The micro gold washing through was an extreme amount.  For larger gold flakes I am not sure if this same process would work, deffinately not on nuggets for that riffels would be needed. Although the experience was a lot of work I learned a lot and also found there is larger gold there in other areas but unfortunately I didnt learn that until the evening on my last day. More then likely for clean up the best machine for this type of gold is the desert fox which I will probably try next along with some other ideas I have. I will have lots of time this winter to perfect a miller table for all the micro gold as I plan on making it portable I intend on finding out just how much micro gold is in that sand ? Sometime later in the year I will head back there for the larger gold. You may want to know your trail you were using to access the beach is all completely washed out so you may want to find a way to manipulate those wooden stairs. I had a hand cart with some kids bike wheels but now know I need larger tires for sure if I ever do that again. I dont think so though as I have found easier ways to set up and deal with the black sands then carting everything down to the beach and taking it all back up at night.

+1 on the panning! 

Panning .... as it was in the beginning, is now and ever shall be ... Amen!

Panning, humans and gold are symbiotic, a trilogy not to be separated during the quest for gold or it will ultimately end in tears of frustration!

Make panning your friend .... then become a gold prospector/miner!

All the proficient gold prospector/miners you will ever meet will be proficient gold panners .... end of story!     [<-panning->]

I used a GC for the first time cleaning up cons from running the large classification rig set up at the Lucky Strike in Marion, N.C. last month.  It did a great job. In the past I have had to re-run to make sure I didnt miss any.  It catches everything I am interested in keeping.  It seemed to be a little difficult getting all the gold out of the mat without splashing it out into the grass.  I found that using a garden hose nozzle and a large cleanup pan that I could manage cleaning the best part of the gold out of the mat.

I heard that they are coming out with a classifier drop riffle set up for the cube. Has anyone else heard this? That would sure be sweet since I was planning on picking one up this winter.

I saw the new 1/8" classifier and spoke to Mike at the Spokane Gold Show in April.  He said it would be out in a month or two but I guess that didn't  happen.  Looks great, fits right onto the top perfectly, but who knows when it will actually be for sale.

Well I ordered a gold cube deluxe from IRL in June after I found out on here who sold them, Thanks.
To my surprise it arrived in 3 days.(orders from Surrey can take 5 days)
Well went up to the claim in July for a week but did not use it much as it requires 1/8 material and nothing larger so just used it for a clean up  sluice after running our reg sluice, worked great for that took 30 gallons of cons and made an excellent super con.
Went back up to the claim in Sept and my brother had put together a 2 1/2 gallon bucket with 1/8" screen in the bottom which he had been using to classify material down and he was quite pleased at how the gold cube eats up the material and saves so much time rather than panning it out for testing.
With that we put a "Red-Neck Vibrator" together and started classifying material with it.
Im am really impressed with the amount of material that the gold cube can run. I also like the fact that the first drop section acts like a nugget trap and the heavier gold doesn't even make it to the matting which holds most of the gold from the material we ran through in the top level and a small amount in the second and hardly nothing in the third,
The few tests we did on the tailings showed a small amount of -100 & -200 gold but it was less than 0.2% of the gold that we  recovered in the run.
There is also a gravel pit on the claim and I tested 60 gallons of -1/8 material from it and found lots of lead but not much gold(as with most gravel pits in the Caribou there are a lot of hunters that need to shoot at something or site in there guns) tested the tailings and didnt find any lead or gold
I'm really impressed with how fast the Gold Cube works and how much it catches

It seams to work really well with the -8 but I'm going to build a new Red Neck vibrator this winter and before I order the new screens am curious how much more efficient the GC works with -20. I think I will need a spray bar on the lower screen if I go that small to help with the blanking off of the screen.

Ray, I have followed and enjoyed your posts for quite some time now. You seem to really enjoy helping people.

I like the equip you have put together and applaud miners making and testing their own stuff.  I think you have hit on a very good formula for pulling that fine gold from the NSR sands <-good_>

I remember taking a course with Wayne Loewen many many years ago now at Devon, and he too liked the idea of the long sluice and had some interesting finishing concentrators.

I am always interested in seeing, evaluating, testing, considering, different equipment and would like to see yours run.  To really have a considered evalutation of multiple pieces of equipment it really does make sense to run them side by side if possible to limit the variables (although there will still be some that exist). Running you concentrator at the same time as a Gold Cube (or other units/mats) to see what the comparative results are would be interesting. All equip I have ever seen works best under certain conditions for certain material within certain parameters. Many times we need different equip for different jobs and seldom is there a best choice for an all round unit that will do everything. I like my Gold Cube so far as it does most of what I want for what I need however I am always on the lookout for what might work better.

If I ever get the chance to stop by on the way to/from SK I'll let you know so we can try that as I will bring my GC and some other items. If you ever come through the Mile Zero City let me know as well.

Not trying to detract from anything you do but it does seem that your post(s) to go 'head to head' with a Gold Cube in particular seems to be more like you're looking for a pi&&ing match than anything else. Just saying.

Look forward to meeting you some day and talking gold, maybe even swinging a shovel or a trowel with 'ya.  Greg

Hey Guys and Gals
Well the Gold Cube adapter that classifies and turns the whole thing into a highbanker is ready.  It's on the site now but we don't have a name for it yet.  We kind of refer to it as a topper but we are looking for a better name.  There has been a couple rule changers wrapped up in the topper as well.  We have always said 1/8" or smaller, by hand this is true.    We added a couple drop riffles to the topper to catch the larger gold and increased the classification punch plate to 5/16 for the ability to run 50% bigger material.  There are a couple videos on the page for set-up as well as watching it run.  Have a look.  
 Gold Cube Topper  (http://www.goldcube.net/#/gold-cube-topper/4567862964)
In the last couple months we have sold a few at the Gold Shows to get it out there and to get some feed back.  It's a hit

Very nice customer service story! Okie has been a big contributor to the forum and I has always felt like he was an extended friend. Why I bought my Gold Cube.
I left my Gold Cube in the garage last summer and it was too hot!! It was set on a chair and not sitting level and the slick plate was tossed to the side on some other equipment.
Well I pulled out the Gold Cube to use it and the slick plate didn't sit on there level. It was warped or racked out of plane. One corner was maybe 3/16" too high and the seal to the boil box acceleration chamber would not seal properly.

So I started thinking "oh man I don't want to deal with this and have to send it back to Mike," but I was confident an exchange or something could have been worked out. But instead I just took the Gold Cube outside in the sun and left it sit all day. Not my first choice as Ultra Violet light is hard on all plastics (even UV resistant) but it worked fine and all is well.
The warpage disappeared and I forgot about it until now.

So lesson learned: try to store the Gold Cube in a cool spot if you can not then at least make sure it sits level for storage!

I hear my dads voice in my head from yesteryear -"Put your tools away when you are done little man!"  ;D

Sorry for the late reply on this LogJam  The Gold Cube will handle water sloshing around in the same direction as the flow.  So set the Cube direction as port to seaboard.  Bow to Stern will have less roll to it.  It will keep the water from too much side to side in the Cube.  I'm sure if it is crab fishing rough, you are going to loose some gold or even the Cube if it's not tied down.  Maybe we could fit it with a gyro to keep it straight....  hmmm................

What do you guys think about using the large Gold Hog high banker vs. the Gold Cube?  Will it be just as effective turning concentrates into super concentrates?

The gold cube uses a lot less water flow then the GH HB. So not a fair comparison.
But yes the GH HB will do a good job making a super concentrate.

The gold cube could not compete with the GH HB due to the thorough put, the Gold Cube could never process the material as fast as the GH HB.

If you were working a beach sand deposit maybe the Gold Cube might have some competition - but not with the average size of the raw material being bigger then 1/8"

The Gold Cube is for reducing LARGE amounts of sluice/HB concentrates to a workable size in my opinion.

My 2 bits...

Title: Re: Gold Cube Technology
Post by: Tom60 on January 02, 2013, 12:13:49 PM
The gold cube will process concentrates better than anything I have ever seen, but it is pretty slow.  The gold hog has an advantage of going through a lot of material fast.  If you watch Gold Hogs videos in Georgia, he is catching the fine gold, but to prove his point, he processes his concentrae tailings with classifiers and a gold cube.  Get both of these and one hell of a lot of luck and I think you would be better off than 90% of us.

Love our Gold Cube..... and if ever lost or damaged would buy another the next day.
We use it every week. If you'll notice in the video talked about, ours is ABUSED and has been used heavily.
(100's and 100's of runs.)
For most prospectors the Gold Cube is the best bet for super concentrating.
We also like to screen to 1/16th and run that way. 
It's small easy and quick to set up, and low water volume.
Our Gold Hog unit really is a high volume highbanker.
It does convert to a super concentrator, but really that mode is for commercial ops that end up with 5 - 20 buckets of cons due to still using moss and carpets.
They only have to screen to 1/2" to run in that mode which most larger ops like.
Even then we recommend they rescreen to 1/16th and run through the cube for very fines.
I think the cube is a better bet for the average prospector.

If you buy the Big unit, then I would buy a 2 tray cube.
If you do several runs with the Big Gold Hog, you'll end up with about 3-5 cups of cons per run.
3 - 4 runs  in a day and you'll have about 1/2 gallon to 3/4 or so.
Then use the cube to super concentrate that down to about 2 cups.
All your gold will be in that 2 cups of cons.

That is pretty much how we run and really the basis of mining.
You are super concentrating over and over.
Funny when you think about it....
Take 5 - 20 tons of dirt and concentrate it down to 2 cups.





 
Title: Re: Gold Cube Technology

Simple answer...YES
Title: Re: Gold Cube Technology
Post by: Okie on January 02, 2013, 03:34:01 PM
I have been in contact with quite a few commercial miners over that last few months.  They are using the Gold Cubes in two parts of their operation.  Sampling, and super concentrating.  One cool story was from a core sampler, he would crush the samples and Cube-it on the spot.  Then send a report that same day, otherwise, it would be weeks.  Digging a pit, a pan is good to see if you are deep enough.  But 4 bucket (1/10th of a yard) in the Cube in 30 minutes from shovel to scale, you have real numbers you can bank on.   At clean-up like jayjayccr said, getting tons down to 2 cups, that is a lot easier to carry. 
The real deciding factor is material volume and gold size.  If your pay size of your gold is 20 mesh and bigger, and you have many tons of material to run through, don't use the Cube.  You need high throughput like the Gold Hog.  If your pay size is 30 mesh minus, you need to start being a bit more careful with it.  Then you really need to stick with the Gold Cube.  If you have both size ranges, use the Gold Hog to shovel in to.  Then capture and re-run or just screen off the 1/8 plus at the discharge of the Hog and run the minus stuff.  Either a flat screen or a small mesh trommel.  It will mean a lot more work so only do it if you are finding most of your gold that will add up to anything(pay size), in the hard to see range.  One nice thing about the Gold Hog is the fast clean-up ability.  Get proficient at the clean-up, do it more often, create concentrates, super concentrate them through the Gold Cube and walk back to the truck without a heavy bucket, in fact, just a baggie of cons with all your gold. 
The right machine for the job, no machine will do every job, so more often than not, you need more than one machine. 
Have fun out there.
Mike

Good question but no.  The blue is too hard, it wears faster. it's difficult to glue and won't stay wet.  The trapped air bubbles block gold from being trapped.  I understand some people like to look at gold on different colors for their pans, but you are really not looking at it like you would a pan.  Colors .............

Certain BLUE vortex (nitrile) has a larger face pattern to it.
(Not all does and it's hit or miss.)
However, it is harder than the black like Mike says.
I wouldn't change anything in the CUBE.
It runs perfect.
Once in a while we'll play around and put the blue in the third tray of the gold hog.

We had a relaxing but tough 2 days.
I was trying to get a better feel of sediment rates for the new Monster Hog.
We ran mostly at a 2 person shovel rate which is about 2 - 3 tons per hour.
Got home and ran cons through the Cube.
You CAN'T see the fine gold as I haven't work down cons from the cube yet.
But nice comparison from the #1 tray and the #2 tray.

Just pointing for scale and trying to get camera to focus better.
I'm guessing couple thousand of pieces in the -50 to -200 range.
Ended up with about 3 cups of super cons and every swirl is just loaded with super fines.

over 20 in the first and 6 in the second all Bering Sea gold.  I don't have a picture but one report was 5 oz of gold and recovered 1/4 cup of mercury.  Us miners are so bad for our part in helping nature.   <-NO_>  Lets not go there though.

Thanks for the estimates... I have a ways to go before I could see a clean out like that!

Interesting in each picture you can see where the low pressure matting zones are, or better where they aren't. Down the middle seems to be where there is more water flow I am guessing.

Title: Re: Gold Cube Technology
Post by: Okie on January 07, 2013, 09:44:58 AM
Its the feed style.  When the Cube is fed by the topper, the gold is concentrated in the middle, if it's a side to side motion, more material is dumped on the outer edges.  Like spray painting, it will glob on the outer edges.  Gold paint of course.  I've also seen people plop on a scoop and let the water eat it away.  this will also take most of the material wide.  So bottom line is the zones are caused by the operator.  I'm sure nobody cares as long as the gold is there when you pull it apart.

Has anyone ever compared the S1 to a Gold cube to determine which system loses less gold?  I know the Cube processes volume much quicker then the S1.  However, people who use the S1 say it pulls out ALL the gold and people with the Cube admit to finding a minor amount of gold in their tailings.  Has anyone used both systems and able to compare them accurately for Gold Loss?

My quick Gold-Cube review;

When the Gold-Cube first came out, I'll admit that I was pretty skeptical ... but I was skeptical more towards the Gold-Cube being used as a primary concentrating device of primarily un-washed bank-run material.

What really got me seriously re-considering the Gold-Cube was all the favorable feedback on this thread ... after evaluating all the feedback on this thread, I could clearly see the value in the Gold-Cube being used as a "secondary concentrating device"... the fact that several individuals herein gave the Gold-Cube a de-facto endorsement, finally convinced me it was worth serious look as a "secondary concentrating device".


My high volume High-Banker can create alot of Black Sand cons over a weekend ... and my Black Sand cons really add up over a season.... and since my High-Banker cons are quite clean, my initial concerns about clay & muck clogging the Gold-Cube machine were essentially no longer a big issue.

After running bunch of Black Sand cons over the weekend, I can say that the Gold-Cube is one of the best dollar-for-dollar hand-fed secondary concentrating devices on the market right now - and I've tried several... on my first run of material thru the Gold-Cube I was able to capture alot of fine Gold (several hundred colors) that my Keene Super-Concentrator could no longer capture (even after re-running the Black Sand thru my KSC 3 times over) .... I also re-ran the Black Sand cons thru the Gold-Cube a 2nd time (at aprox. a 25% lower water speed - I installed a ball valve to control water flow) and only captured a few colors ... this tells me the Gold-Cube captures an extremely high percentage of Color first time thru the machine at it's factory setting.

Some things about the Gold-Cube I like;

* The unit is fairly light,
* The unit is easy and quick to set-up,
* The angles and water speed are pre-set,
* The machine has a small foot-print,
* It captures a very high percentage of the Gold on the first run ... you don't have to re-run material over and over again to extract a very high percentage of the color,
* It processes cons at a very quick speed,
* The machine is essentially idiot proof.


As a hand-fed "secondary concentrating device", I think the Gold-Cube is probably the best value on a dollar-per-dollar basis for visible Gold down to aprox. 200 mesh in the Hobbyist market today, it's also one of the quickest and easiest to operate hand-fed secondary concentrating devices on the market .... for around $500, I just don't see anything else on the market right now that can fully compete with the Gold-Cube for capture rate/speed/ease-of-use/cost ... the next step up are the Shaker Tables, but they cost many times the price of a Gold-Cube.

As a hand-fed "primary concentrating device" (even with the Hopper) I don't think the Gold-Cube would be your best bet - a high quality High-Banker would process alot more material alot quicker ... it's possible that you might be able to rig/attach a couple Gold-Cube trays to the end of a High-Banker to increase the capture rate of a High-Banker - not sure though, haven't tried it yet.

Bill Carson - excellent review!

One thing did stand out that I wanted to point to.

... I was able to capture alot of fine Gold (several hundred colors) that my Keene Super-Concentrator could no longer capture (even after re-running the Black Sand thru my KSC 3 times over) .... I also re-ran the Black Sand cons thru the Gold-Cube a 2nd time (at aprox. a 25% lower water speed - I installed a ball valve to control water flow) and only captured a few colors ... this tells me the Gold-Cube captures an extremely high percentage of Color first time thru the machine at it's factory setting."


If a certain set of recovery factors catches so much of a certain size Gold - why doesn't it capture all of it?  What makes certain pieces of Gold so very different that they're not caught the first time through? 

My thinking is that those occasional pieces of Gold are fixed to a light piece of gange.  Going through the (in this case Gold Cube) equipment, itself, works the Gold piece loose from the 'host' and this freed piece is what is caught the second, or third time through.

I think it could be related to variable factors such as feed rate and Black sand content .... I was feeding the cons thru at a fairly aggressive rate .... so sometimes, the Black Sand slurry may be a little thicker at times when going thru the machine - which would make it a little more challenging for small particles to drop-out.

I typically stir my cons in a bucket at a ratio of aprox. 10 to 20 percent water to cons .... essentially I pre-stratisfy the cons in a bucket before it goes into the gold-cube .... instead of shoveling the cons in with a small hand tool, I typically pour the con-slurry into the Gold-Cube machine slowly via a small bowl - and I continue to stir the main cons bucket periodically to keep the cons in a pre-stratified slurry.... sometimes I pour it in a little quicker than other times... and when you get down to the bottom of the bucket, the Black Sand tends to be more highly concentrated.

One fault I do have with the Gold-Cube is; when running in re-circ. mode, I can hear the pump load up a bit with sediment after a little while ... the People from Gold-Cube may want to work on some sort of screen or screening-device on the pump to help alleviate this issue - I'm sure I'm not the only one experiencing this issue.
Title: Re: Gold Cube Technology
Post by: islanderca on February 15, 2013, 10:00:30 PM
The gold cube is an excellent piece of equipment.  I have one and I love it.  Mr. Carson, if you run two buckets for re-circ instead of one, you'll clear up most of the pump issues.  If you had a finer screen at the pump it would just plug up.  Use a tall rubbermaid storage container for your primary sediment catch, cut a 2 inch notch in the middle to create a waterfall into a shorter secondary container that you put the pump in to re-circ.  When I run a one bucket system I ill put the pump as high as I can in the container to help with the plugging problems and it works till the bucket is getting full of tailings.

Hey guys, check out this new gadget coming out at the end of November:



It concentrates a thousand pounds of dirt down to about a pound of superconcentrates with less than 1% loss of gold.  I don't know yet how much it's going to cost; have an email inquiry in to them now.   Make sure you check out how it works; pretty fascinating stuff.

Looks interesting ... but if you look at the sand they are using in their demo; it contains virtually no clay ... in the real world where quality Gold bearing river sand resides near bedrock, there's often a certain amount of clay to contend with ... I think the "trough" area of the Gold Cube may face "plugging" issues (even if the sand is classified to 8-) if being fed with sand that contains a certain minimum amount of clay ... one way around a clay-plugging effect might be to thoroughly liquify your concentrates/slurry in a bucket before adding to the Gold Cubes' slick plate... hopefully they've done some R&D with clay'ish sand and have some solutions.


Acctually I have just bought one and the best use for it is after a weekend running the sluice and doing a few cleanups, run all that sandy material through the cube and it really cleans out 98% of the black sand leaves you with just a little for panning. most of the gold I recovered with it got trapped in the little troughs instead of the matting.

Just bought one and ran some dirt through it. Sure saves a bundle of time knocking down the material into a cup or so of concentrate. You only need the 3 stack which is the slick plate and 2 separator trays but I got the 4 stack deluxe. Very solid construction. The wife went out shopping with her Aunt so it was a good time to set it up in the kitchen. I didn't get too much water on the floor when the hose came off because I didn't hook it up right. Nothing a few towels couldn't clean up....

The S1 and Gold Cube have different uses. First of all from what I read the Gold Cube has almost NO gold loss down to about 200 mesh with the 4 stack. But the Gold Cube is used first then you take the about 1 and 1/2 cups of concentrates from it.

Then secondly run this through the US Prospector S1(Micro-Sluice Jr., Micro-Sluice 1, Bucket Sluice Concentrator from California Sluice Box, Angus MacKirk Sidekick, Brawn Power Concentrator Mini from ProspectorsPlus, Tom and Perry's sluice from the GPAA, or Gold Extractor from the New 49'ers - Dave McCracken) down to teaspoons or tablespoons of concentrates.

Then thirdly and lastly use a Blue Bowl set up or type of Miller Table(homemade, Black Magic from ProGold Prospecting, Catch-It II water table, Brawn Finisher from ProspectorsPlus, or Broom Hilda from Angus MacKirk)  for clean gold ready for sale so mercury does not have to be used.

A Microwave Gold Kiln Kit with flux can also be used.

It's a Super concentrator. Takes the concentrates from you're highbanker and reduces them to a fraction of amount. Then you pull out the black sand with a magnet, then miller table.

Not for everyone but yes for me. But yes you can go directly from the Gold Cube to the Miller Table or Blue Bowl. I have a Gold Cube, a type of Micro Sluice, the Gold-n-Sand magnetics remover kit, and a Blue Bowl. Now I want to purchase a type of Miller Table for clean gold finishing instead of the Blue Bowl. I think the Black Magic from ProGold Prospecting is the best one to get.

A friend brought some Oregon dredge cons very black no visible gold very heavy.  I find out after the run that he ran it through a blue bowl first then came to me.  On the first run I got about the same as he got from the blue bowl.. reason for the blue bowl loss 30 mesh water speed and 100 mesh and smaller gold blown on through.  He was impressed enough to order a Gold cube the next day.  On ocean sand also very black and run as primary tool some very fine gold and a lot of fun with #4 digger (Grand kid) Show and tell was AWWWWSSSSOOOOMMMEEE for him and his class, I get a digger for life fair deal.

Hey Bubby-Joe,

While it's a pain to do - I just go to a word processing program (I use Word) and write without worries.  When finished (spell checked and such) I copy the stuff I just wrote (control+c) and paste it (control+v) into the reply screen here.  You'll never have to worry about loosing a post that way.  If  something goes awry in that process you still have the original word processing file to re-copy into your second effort.  

When all is said and done just close the word processing file without saving it.

Let's figure this out:

We have to set everything up wrong to get gold in the tailings.
Make sure your mat is full of bubbles,
Make you water less than 800 or more than 1800 Gallons per hour.
Classify to 1/8 inch and only run the big stuff.
feed it 1000 pounds per minute so the material runs over and burries the Cube.
That should get you plenty of gold in the tailings for sure.  LOL

How much gold have you gotten from your Gold Cube so far?

When I was first informed about the gold cube a couple of years ago, I held a fair amount of skepticism in reserve.
At the Quesnel  gold show last spring Irl had one they were demonstrating, it looked alright but I was still not entirely convinced of its claims.
Well Lakelady ended up with one under the tree this holiday season, She put it straght to work processing all the cons and black sand that would be real nasty stuff to pan out otherwise.
 The gold recovered from it was quite considerable, that we might have otherwise neglected.

I am now highly impressed with it

The big problem now is after playing with the gold, the fever has struck again, we have no dirt left to play with, and a spring thaw is still a long way off to get more.
It is way to early to be in the throws of Cabin fever... Dag Nabit !!!

Great testimonial LL I understand the position this puts you in and all I can say is sorry, (snicker) I have another customer las season in the same predicament. Over the years he had been throwing all is finished cons in the driveway.  Looking for some dirt he saw where the snowplow had rolled dirt into the banks and figured any dirt was good enough to play with.  To his surprise, there was gold in the 2 gallons he was able to collect that afternoon.  He called me up and was a little upset with me.  Claimed he was going to have to dig up his entire driveway this spring.  I tried to calm him down with a couple observations.  This year if he mined his driveway, he would at least be closer to the bathroom and the refrigerator.  He admitted I had a point there and said he would report back in the summer with his finds.  It was last fall that he did report back.  He ended up with 14 oz of gold.  He dug up the entire driveway (wife not happy about that) and ran 35 years of spent cons to get it though.  Said he was now too spoiled mining so close to the recliner that he forgot how to load the truck. 
So I guess you could take out a weed torch and loosen up some material or some coals from the fire under a metal watering trough to warm up some earth where you dump out your cons.  Anything to cure the cabin fever right? 
Again thanks for the great report.  Live long and prospect

This looks like a well thought out piece of kit! I am not sceptical and everything that needs saying about this equipment has been said, but with every gold rush it seems that the suppliers of gear, grub and guns seem to be the only winners!
The plain fact is sluice boxes made of wood with miners moss and expanded metal work just fine. If you are into bad clay you need to puddle it or make your boxes longer. If you need to catch smaller gold, throw in some rubber mat and maybe another 8' of box. You can make all the claims in the world about a better wheel but in the end, they all do the same thing... Roll.

Hey there, Dragline!

Not to belabor the point - but - the original thrust of the topic here is using the 'Cube to reduce classified concentrates to final, easy, pan-out. 

The 'Cube is generally accepted as a genuine wiz-bang, super-duper, does what it claims to do, in a fast and easy way piece of equipment.

Just as your new-fangled Moss 'n Expanded is head and shoulders above carpets and riffles, better equipment is just better.  Would you go back to riffles over carpet?  I suggest, no.

I totally agree! I only intend to point out that while new technology is wonderful, the cheap old fashion stuff can be equally good if used in the correct manner. In addition while the gold cube may be exceptional as a clean up tool it may not be practical in a bulk sampling scenario, where two men with shovels need to process as much material as possible in a short period of time. The cube may be best left at home for final clean up, and perhaps suited for a commercial operation to reduce concentrate. I would consider owning one of these simply to reduce clean up time or as a small beach placer wash plant.
I hope I was not misunderstood if so I apologize. This appears to be a great product.

Without classifying the machine will not operate the way it is intended. That is not to say the machine isn't doing the job right. It was never intended to be fed at high speed with rocks and clay.

Uuuum... i was thinking that was the purpose of the topper, to allow only material into the cube that it's designed to handle. The video of the Gold Cube with the topper shows it being used right at a stream.
Maybe the designer can provide some feedback here, thanks.

The material doesn't stay in the hopper long enough to be effectively washed if it was laden with clay. The spec of 95% recovery while great with concentrates or sand will not be the same with clay packed material. That is why trommels and shaker plants were invented. A person trying to convince me that you can chuck a shovel of blue clay wrapped boulders into a hopper and with no scrubbing recover 95 % of the gold locked up in it is a bold faced liar! Fortunately I don't believe the maker is selling it like that. He has be forthright about its intended performance.
It is important to realize a very simple concept. Mining is a volume game! If my wash plant has 95% recovery but can only handle 5 shovels of pay dirt in ten minutes and your crappy wash plant has 70% recovery but can handle 10 shovels in the same time period who will get more gold at the end of the day? Does a large mining operation get all the metal? No that's why we are now mining their tailings but they obviously did good enough to make millions of dollars! Because they could run volume. Quantity over quality.

 Hello guys.
If you dont mind I will jump on in on this topic.
Depending on the meteral the gold cube can be a primary tool.
For black sands and small gold, the cube is un-beatable. but for larger gold the cube just is not designed for that.
I recemend that for large stuff (like your clay) to use a wash plant/high banker/sluth box... and to put the Gold cube with a screen or topper unit, at the end of your
run offs.
Rippels ketch gold but thay cant hold on to the small gold, and that is what the cube dose the best.
Just my two cents worth of it.
Have a good day.

i used the gold cube and the gold wheel and incorporated them both with my setup last season here in western australia where i was using a commercial dry blower
and found that i lost a lot of gold out of the gold wheel and hence we have modified the gold wheel awaiting some trials to see if the retention and pickup rate will go over 95%.

The gold cube took the concentrates out of the gold wheel for further processing and yes it picked up the gold that the wheel didnt pick up.

I run my dry blower for 6 hours a day sometimes longer sometimes we r broken down but after the days work loading the dry blower with a Backhoe i take the
the 4 large riffle trays out and put the concentrates in a large tub then we put this material through a crusher then we put this material through a 151 dry lower to get a fair amount of the clay dust out then we will put this material through the gold wheel and once that process has been completed we put all the material from the gold wheel back through the gold cube evry weekend --just to get all the gold.

this system works well for me and yes the gold cube is the best piece of sliced bread that i own.

i like to see the gold rising up the gold wheel coz this gives me a very good indication that our work for the day was worthwhile.
the cube can be a pain trying to get all the fine gold out of the mats.

I can relate to the problem getting the fine gold out of the mats.  I only use the cube for final cleanup at home.  That way I can use a garden hose with straight nozzel to flush the fines out of the matting.

As a primary piece of equipment, the Gold Cube needs to have material classified to #8 by hand and then fed into the Cube with a scoop.  With basic river bottom material it will rip through 1000 pound or 16 buckets in an hour.  It's best not to go that fast but it can do it.  So when we first arrived in the market 3 years ago, unless you wanted to classify everything by hand, the Cube helped with the clean up instead.  Not everyone felt that way so there were many who used it as a primary from the beginning.  If your gold is minus 20 mesh, if you use the Cube as the primary, you will come home with more gold. 
Then came the gold Banker last year.  With the Gold Banker, you can shovel everything right onto the top plate and all that makes it through the #6 mesh holes will feed the Cube.  On the way to the Cube in the Gold Banker body/pan, there are 3 drop riffles.  These will allow you quick inspection to see if you are in the gold.  This is also where you will capture the biggest gold. 
Clay has always been a problem so have a look at this video and see the chicken gizzard effect on the Gold Banker to dissolve the clay.

Don't push it through, just let the rocks grind it up and the water will process it through the Gold Cube. 
After yo have a pile of plus sized material that was classified out using the Gold Banker or the hand classifier, I use a metal detector and a plastic scoop to check for gold.  Scoop and scan, no beep, no keep.

That is the same hopper (10" wide model but bare) Okie uses to make his gold banker hopper. You must use 3/16" classification.

Title: Re: Gold Cube Technology
Post by: Okie on February 07, 2014, 11:08:29 AM
Our plastic body for the Gold Banker is similar to the CA Sluice design but ours is made in Denver and has 3 drop riffles moved closer to the discharge.  This creates a longer slick plate surface to create a more laminar slurry.  The Opening to drop into the Cube is widened to eliminate the side lips that could transfer material off the side-ends.  More of a lip was created to mount more securely as well.  The CA version will do but not as well as the one we make. The punch plate is 3/16" and you will have to make sure it has real tight holes, close together.  If they are too far apart, you will lose a lot of water and material off the end.  You will also not have as many open holes needed to do the job when the perfect size rock starts blocking holes. 
Just a few things to note.

A friend of mine bought the Gold Cube and was all Gaga over it. It now sits on a shelf. He said he spent too much time feeding it and he had to run his material (classified) through it about 3 times to get most of the gold out. The Gold Cube, like any device, is a wonderful tool but, I am already looking for a better time saving gold clean-up device.

Oh, I was on the Quartz Creek movie set of the Hoffman's Gold Rush and I seen a lot of gadgets in and around the clean-out tent. I was told; "we get all kinds of gizmos sent to us for free"...(with the manufacturer hoping to have it spotted on one of the episodes). I seen the little kids playing with a few of these in the community sand box. That's "show biz" folks.

If someone is spending too much time "classifying and feeding" a Gold Cube, then they are probably trying to use it as a primary concentrator (high-banker) , instead of using it as a secondary concentrator.

The Gold Cube is very good as a secondary concentrator, (what it was designed to do).  But impractical as a high-banker , it is severely limited by its requirement of 1/8" in-feed. 

Title: Re: Gold Cube Technology
Post by: JOE S (INDY) on September 07, 2014, 10:45:33 PM
BPN,

100% correct.  The 'Cube is a concentrate concentrator and not a primary recovery unit.
Title: Re: Gold Cube Technology
Post by: Okie on September 08, 2014, 09:54:36 AM
The Gold Cube is a wonderful concentrator but don't cut it short.  The size of the gold in your area will determine what machine should be the primary machine.  The mentality of more dirt equals more gold is 49er mentality.  If you are in the Mother load and all you gold is the size of rice and bigger then that is a good plan.  If all your gold is the size of fly poop then all that big equipment will blow out all your gold, you will end up with some but not most.  This is where you will have to decide if you want more dirt or more gold.  I have worked next to a high-banker in this itty bitty condition.  After 5 hours the bucket count was at 4:1 in favor of the Highbanker but the gold count was different.  They had just over a gram and were thrilled with the best they had ever done.  The Gold Cube clean up was 1/4 oz not weighed but is was 1/4 of a 1 oz vial.  Now looking at each of the gold takes, it was easy to see that the gold from the Cube looked like someone poured gold paint and set a couple chunkier pieces in it.  and the High Banker take was mostly chunky with a few fly poops as well.  The bottom line is: You need to analyze your gold in the area you will be mining and optimize gold recovery by choosing the right machine.  No the Gold Cube will never, always, be the right machine.  But if you never consider it a primary, you are missing out. 

To get closer to being considered a primary we have the Gold Banker that sits on top.  No more shaking a screen over a bucket.  "shovel ready" 
And at the end of the month we will have a Trommel on the market that will truly make this a one-man primary mining operation. 

A huge thanks to all our customers and friends out there.  Gold Cube has become.  October we will be 4 years old, how time flies!

I used a Gold Cube with the Banker hopper quite a bit and the Gold Cube IS fantastic at catching gold, it is great. But my complaint was the Banker hopper attachment was far, far too slow to keep up with the Gold Cube and material had to be cleared off of the punch plate by hand. Now with the new 5" inch Trommel attachment(Lil Monster), made by Gold Fox USA, is available, that is THE one to have and that IS what I would buy for a Gold Cube for real fast production!! and breaks down clay, cemented gravel, no double handling-hands free on the material, and washes rocks much faster-better!!

The Gold Banker top attachment use to have 3 plastic drop riffles before it hit the Gold Cubes slick plate tray. Does the new Gold Cube Trommel attachment screened at 3/16" have any type of riffles to catch gold sized from 1/8" to 3/16", before it hits the Gold Cubes slick plate tray and catchment trays.??

Had a couple liters of cons that I started cleaning up thinking I wouldn't bother with the gold cube. After the first few pans I quickly moved over to the cube in the corner and ran my cons through. So nice to cut them down to a cup or so from several in a couple minutes. Makes the 10 minute setup more than worth while. Also I do pan my tailings quickly just to make sure I dont leave anything behind. There is usually a few bits, but nothing to worry about.

Never too few cons to make a cube run worth while!

Hello Crow
Usually I will only find gold in the tailings if I am in an area where the gold is real flat as well as small.  Add in some really heavy host material like black beach sand and there will be some loss (a % or 2).  That all being said, all you have to do is remember to make sure your mats are bubble free (video #4) Bubble Video (http://www.goldcube.net/#/training-videos/4582672295) and make sure that you don't over feed the Cube.  River gravels max feed is about 16 buckets, black beach sand is about 5.  Both piles will weigh the same, so remember, it's the weight that you need to pay attention to.  Glad you like the Cube, we sure do, LOL

Thanks Mike,
I may have been guilty of overfeeding but no more since I’ve been enlightened!  I do go the extra mile to ensure no trapped air on the mats.  However, both of the conditions – small and flat do apply to my area.
I wanted to go thru a lot of material I processed before I got the Cube but unfortunately it’s been incorporated into one of Management’s flower beds and as a matter of my own personal health and well being, I better just stock pile new material!
You and Red have done an outstanding job with the Gold Cube.  Stand by, we may be takin’ you on full time any day now !!!!

We've had loses of 10% and more on our WA beach sands through the GC. I've had my tailings and each tray run on a wave table to see what was happening. The results were 40% caught 1st tray, 30% 2nd tray 20% 3rd tray 10% loss. This was material directly off our beach not cons or pre run material. If you test with pre run material you are dealing with gold that has been caught before. Some gold just doesn't like to be caught due to it's shape. If you're checking your tailings and have really fine gold you will also see fine gold wash out of the tub or bucket you're catching them in and into the outer tub or on the ground so that's also something to think about when testing your tailings. I'm not trying to knock the GC but just being realistic on the material I've run through it. Dirty water and clay will really plug up the matting also so try to keep your water clean, as we found out on testing at a commercial placer operation that was recycling water. If you're not dealing with lots of fine gold don't worry. If fine gold is your primary concern I'd be more concerned. Hope this helps without hurting too many feelings.
Title: Re: Gold Cube Technology
Post by: Okie on January 06, 2015, 08:37:28 AM
Thanks for the input Doug, no feelings hurt that is for sure.  This is a real world thread and I have been to Cape Disappointment there in WA and have played with the same stuff.  There and Lake Superior MI are the two holly-crap locations I have encountered for gold retention.  One of the ways I analyze a condition is a devise I have called a drop-zone.  It is an 8 second device that will isolate the deck once every 8 seconds.  It uses a teaspoon of material for the test.  The typical result is there will be most of your gold in the 1st second isolation.  Then some in the 2nd and in the 3rd you will start showing black sands and so-on until the 8th second where it will show blondes and silt with no black sand or gold.  Here is what was found on beach gold.   1st second, less than 5% of the gold.  2nd second there was almost no gold and black sand already showing up. 3rd second was a huge dump of black sand and still almost no gold.  The majority of the gold was found in the 6-7th seconds, way behind the black sands.  Why?  Shape!  All of the black sands were round and were able to drop straight down.  The majority of the gold was very small and extremely flat.  It would flitter/flutter through the water and take it's time.  In a riffle situation, you are doomed.  In a Gold Cube you stand a chance because of G-force and Vortex.  If you need better than 90% on the beach there are only 2 things to do.  Slow your feed rate down and get a higher percent retention, but at the end of the day come home with less gold weight.  Or add another tray, maintain the same material rate and gain at least another 5% or more. 
Doug makes very good points,
The one I like is "Some gold just doesn't like to be caught due to it's shape."  No truer words for sure. 
Also his points on the finer the gold the cleaner your water needs to be.  Dirty water acts like oatmeal to fine gold, if it can't sink to the mat, it's gone!

Thanks for your input on this Doug, no two locations are ever the same and some, for sure, need special attention.  In a river situation or closer to the source of the gold, gold acts like gold, and offers a little forgiveness.

had the opportunity to use the cube. ran material yesterday, was not impressed. as in all things one must try and try again. ran material today at a slower feed, less amount in the laddle and more liquified into the slick plate. 2/3rds of a 5gal. bucket down to cup and half of con. there was a lot of blacksand. after cleanup was quite impressed with the results. right down to super fine flour. can now run this concentrate through the oscillating sluice which will recover 90% plus in the first compartment clean. the rest can later go through a shaker table. the only black box in mining i have seen work. quite the innovated design. did 4 pans of tailings and found 1 piece of gold. your right about the weight factor. make sure the mats are well soaked first. excellent work guys.

2. roll the dowel down the water tray slick plate and it will jamb and dam up the water all but an inch on either side.
3. With the water on, you will see the water getting deep above the dowel.
4. Watch the scooped out section of the plastic that forms the Cube side openings, the water should not overflow out those sides. 
If it stays contained, you are good.
If it overflows out the sides, you need to dial back the water with a valve.

Hope this helps, let me know if there are any questions

My shiny new Gold Cube Trommel arrived today.  First thing I did was take into the shop and start welding and grinding on it.  I added three beater bars inside the barrel to help roll the rocks and gravel inside the trommel.  On all the videos I looked at on youtube, it looked like the rocks just slide down the barrel and out the end.  I hope the bars I welded to the inside help to flip the gravel over rather than just slide around inside.  I'll let you know how well it works after I try it.  Hopefully this will help with cleaning up highbanker cons from several days running.

Nice mod Pepito,  The only concerns I have are the paddles will pick rocks up and jamb them in the spray-bar.  Please keep us informed as to how they work.  Mike

When I was using the Gold Cube I classified my material down to 1/8" like they say you should. But because I don't mind the classifying process at all, I wished I had gone down to -16 or -20 before I ran my material because it is generally accepted that the smaller the better for the Cube.
So now I have a bucket of material that is -16, and one that isn't (-8).
Should I run the bucket of fines through the Cube first, or does it matter??
The reason why I ask, is even when I was cleaning the Cubes matting in the backyard with the garden hose, I thought to myself, " I wonder how much micro-material get's pushed deeper into the matting by the water pressure". And when I cleaned it out in the field, I KNOW I didn't get it all out of the matting from one run to the next (wimpy hose/pump).
Would running the course stuff first block the finer second run if the mat is not 100% completely clean, please?

And is there a thread that has miners debating "Gold Cube Material, Wet or Dry"? I wouldn't mind reading that!
Title: Re: Gold Cube Technology
Post by: Okie on February 02, 2016, 09:39:28 PM
Hello Finder!
1/8" is the size that will run best through the Cube and will allow you to get through the most material as possible as quick as possible.  If you are out in the field and running, it is best to stay that size.  Otherwise you will be spending all your time and effort classifying.  That small gold will settle in the vortex and stay put even with larger material there.  Now if your Cube is already full of gold, (terrible problem to have) the finer gold will be the first to go.  This usually happens around 35 OZ.  So be careful LOL.
 
When you are home and running controlled batches or running cons, sizing your material will give you some advantage.  If you are running milled material, it is best to run everything 30 mesh minus in one batch and everything else up to 1/8" in another or send it back through the mill.   Do a clean-up after each run and it won't matter which one you run first.  In my Cube, I have gotten 400 minus gold and just used the 1100 pump to spray it out.  If you feel there is still gold in there, use a soft bristle brush to dislodge it and spray it again.  Personally, I never use a brush or high pressure water. 

As far as wet or dry?  If I am out in the field, I use a goldbanker or the trommel and it pre-wets the material before the Cube.  If you are running small batches of dry, you can just sprinkle it back and forth across the water flow and all will be well.  If you feed too fast you will get clumping, that could carry some of your gold further in the system.  If you are classifying to 1/8" dry with a screen and bucket, those 1/8 balls could have hundreds of smaller pieces, including gold stuck in there.  If it does not dissolve right away in the Cube,  it will act like a light mass instead of heavy gold.  That means it will flow right on through.  Then when you do a clean-up and check your tailings and find gold, you will think the Cube was set wrong or not worth a crap etc.  So, make sure your material dry dissolves quickly when wetted.  otherwise you will have to pre-wet to get things dissolved and liberated so your gold will stay in the Cube on it's first run.  If I am hand classifying in the field, I use a 1/2" at the dig and then 1/2 fill a mixing tub with water. set the classifier in the water and add dirt and twist and shake it.  This will give you the pre-wet as well as allow any vegetation to float to the top of the larger rocks in the bottom of the screen.  When you lift out the rocks you remove the vegetation as well.  Now just feed the material with a scoop as normal.  Bottom line, pay attention to your material, do whatever it takes to segregate it into single particles and gold will act like gold.

Have fun out there,   Mike

Hi.I do not care how you slice and dice it.Trommel or not.The cube is a finishing device.The trommel still classifies to 1/8.Do you want to move material or do you spoon feed all day.Just saying.Better off with a good quality high banker.Clay will be a problem no matter which way you go.Watch all the gold hog vids before you waste your money.Luck Mcbain.
Title: Re: Gold Cube Technology
Post by: Okie on August 10, 2018, 01:41:58 PM
Clay is a big issue.  There is no better portable solution in the field than the Gold Cube/High Banker solution.   Leave a layer of gravel on the plate, add the clay material and push it around.  The gravel will roll and grind the clay into a milk.  As soon as it is ready to give up it's gold it will be on it's way through the Cube.  When all the gravels on top are clean, you know you are ready for more clay. 
I used to use a paint mixer and a bucket but found that even after I made a slurry of the clay, it would coagulate back into clay before I could get it run.  The banker sends it through as it is ready. 
The small trommel we have is not suited for clay.  It's purpose is river rock.  And it will flat wear you out!  Now if you  have 3 or 4 shovels going, obviously you will need a bigger machine and it better be able to handle a gas powered pump.

Now both the Gold Banker and the Trommel are going to discharge everything larger than 3/16" and for that we have a brand new unit called the Nugget Zone.  It will handle all the large tails and process out any nuggets trying to attempt "Catch and release"  Have a look here https://www.facebook.com/Nugget-Zone-By-Gold-Cube-2226047554078770/

Although the Cube line of equipment is an awesome finishing system, it's mobility, ability and accuracy make it a go to primary system as well.   When you are in an area that all your gold is 50 minus, why trust a machine that can go through a "lot of dirt" with "acceptable loss"  When you can grab a #2 shovel, not a spoon, and get a higher yield with less dirt moved use a Cube system.  "Cube it, or lose it!"

I was kind of surprised to see this post on the gold cube. Is this the first time some of you have seen it. It's been around for a bit. Doc at Gold Hog is a fan of them. He built his own concentrator multi sluice now but used to use the Gold Cube. Kim the owner of Kimanski Gold Panning Supplies is a retailer of them here in Grand prairie. She has had demo days down on the Smokey River and brought out a bunch of equipment. I saw the Gold Cube in action there. Works like a hot dang. It has a screen fixture you can't get for the top so you can run unclassified material on it. Just as good as a high banker.  You can also buy a Gold Fox Omni mini trommel and mount it on a Cube. They are very versatile little units. I may get one yet.

Hi.I amnot kocking the cube as a finishing tool works great.But when I am in the field I want to move as much material as possible by hand.2 to 3 yards min.My hi banker does that and retains the finest gold.Yes I can spend the day classifing a bucket down to 1/8 minus but what do you have at the end of the day?You got a bucket of very fine material that might have 1 spect of gold.You just wasted a whole day and about a 1000.00 to learn that.Each and every tool has a place and the cube is still a finishing tool.So lets go mining.Luck Mcbain.

I bought a gold cube about 5 years ago, but was quickly disappointed when I realized I had to classify everything down to 1/8.  The next year I purchased the trommel that fits on top of the gold cube so i wouldn't need to classify anymore.

My 2 cents:

 The trommel worked okay but didn't wash everything clean so I had to make my own spray bar and the little electric pump is not quite enough to wash the dirt properly so I pickup up a  1" gas pump.  Worked okay but the cube gets top heavy when you add the trommel and would tip sometimes when you shovel dirt in the hopper.  So I had to build a wooden frame to hold everything together.    The problem now is it's bulky and heavy to carry anywhere other than close to the road.  I now have to transport the cube, a stand, hoses, gas pump, gas, 12 volt battery and all the other standard stuff like shovels, pans, buckets, etc.  The other thing is any gold bigger than the 3/16" in the trommel will just roll off the end be lost.  I began designing a small sluice that attached to the wooden frame so any larger gold pieces coming off the trommel would be caught in the mat.  The water pump wasn't big enough to run the trommel, cube and sluice so I put the ideal on hold until such time I get a bigger pump.

Bottom line:

I like the gold cube and it works great with fine material but for my purpose I should have gone with a high-banker.

Seems like the Gold Cube is a great unit if used in the right context. I can imagine people using it and being disappointed thinking it should be able to do something it's not meant to.

Can't wait to get my hands on one.

I have purchased the 4 stage deluxe Gold Cube with the classifier add on and would like to use a metal detector to sweep the tailings before discarding. I have a T2 with an Ultimate 13 coil and an Equinox 800 with the stock 11" coil. Are either of these suitable for this task given that the soil is moderate to highly mineralised ? Any suggestions for a better detector for this purpose ?

Thank you

Thank you for your response ,  I have only asked two question here or on any similar site and have no intention of going to BC or heavy mining at all. I have my Ontario Prospector license and have never thought of anything above a small sluice so I don't know where you saw those questions.

 I have never thought of panning outside Ontario let alone staking a claim. In Ontario it's 400$ of assessed work minimum for each cell per claim anniversary so looking at staking a claim after going through an initial claim and land rights check without so much as a walk through wouldn't really make sense to me.

I have lived in BC about 25 years ago but that was a 3 year Fed gov contract for CFIA and then 2 years with Northern Affairs (don't know what the dept is called now) .

I bought the Gold Cube with the classifier attachment and agree after some testing that it is a finishing tool only but a really good one.  I had to add a Gold Hog river sluice with an aggressive mat which requires more water so I have a gas pump feeding a "Bucket Buster" setup @ 3000 GPH with the Gold Hog feeding directly onto the Gold Cube classifier tray.  The "Bucket Buster" classifies it down to 3/8' which is good for the Gold Hog once the angle and flow are adjusted.  @3000 GPH it works at a shovel full of unclassified about every 10-15 seconds with moderate clay when I ran a test of it. I have to take it out in the field and adjust of course but it looks very promising.  Total cost 2200$ CAD so consider this when you are looking at the "Complete Kit" with trommel , classifier and Nugget Zone.  It will give you a slower sluice that is limited in material passed each hour to a classified scoop at a time.

Post by: JOE S (INDY) on June 10, 2019, 02:49:54 PM
As I understand it, The Cube was originally thought of as a way to process classified concentrates generated from some other piece of equipment (say, a highbanker, sluice box, dredge or such).  The tiny sized Gold in the Arkansas River was the 'Object of the Exercise" and "The Cube Guys" did a magnificent job!   [-1st-]           

The brunt of the work was done by the primary recovery equipment, meaning that a fair range of sizes could be run through the box without having to classify ALL the run material.  Lots of material run through the primary unit left just concentrates be finally processed.

Once the clean-out of the primary box was completed then the +1/8" was hand panned (relatively fast and easy) while the -1/8 was run through the cube.  The cube was fast and operated easily in reducing the -1/8" to a very small volume with a very high % of Gold to black sands.  Then minimal hand panning was all that was left and a strong magnet (like a Neodymium magnet) made just Gold the final product.

Then, miners wanted a way to convert the concentrate cleaner into a highbanker , and later into a trommel. 

Yes, the "Cube Guys" successfully created the equipment that was asked for - but the dynamics were now predisposed to be used in a very small, slow and controlled operation.  That was fine for some but not-so-good for others.

In my opinion, for me and where I work, The Cube is a valuable tool in hyper-concentrating previously recovered concentrates with very small Gold.  For others, the "one stop shopping" modifications are just what they were looking for - and so - no one is right and no-one is wrong.  Win-Win!   {cool^sign}

Like ALL equipment - there is a certain range of input parameters that The Cube requires to work efficiently.  Too fast or too much water or input material can "Goober-Up" the system and, like any gravity system, pass some Gold right through it. 

Beware well intentioned, but sneaky-bad  "Goobering"!
