I like this design a lot!  {cool^sign}  [-1st-]

What is the difference if any between the fluidized bed and an alluvial tower? (I think that is what it is called - like my quicksand concentrator)
In the quicksand concentrator it is a vertical pipe that suspends and pushes out the lights... (versus the fluid bed horizontal design)

I want to see more of these!  <-hypnotized->

Pros and cons? Anyone?

Yep need more input so I can build something like this too!


Water Column Separators
That is a link to a water tower discussion.
The main difference I see is that a fluid bed lets the heavies settle down and an E-tower suspends all the material in layers and should only let gold drop out.
As for cons there might be more cons to deal with depending on how big your bed is. Like the other post shows a smaller clean up fluid bed to run cons might help cut these down.
I also feel if the system isnt balanced gold could be lost. To much water coming up to fast may not give the smaller gold time to settle and not enough will cause the bed to pack up and give the gold no place to settle.
My plan is to test a few different styles next spring buy running the tailings through my sluice.
Here is a link to a drop trap fluid bed sluice you might want to check out too.

Ok thanks - I found the term is 'elutration column' not 'alluvial tower' haha. I understand the concept now much better from the old thread GollyMrScience wrote up.

Thanks again - gives me something to think about today  ;D

I had no idea people could run these after a highbanker....  <-shock_>

Thanks for all the replies guys, I haven't had time to test it yet since changing it over to conventional spray bars with 1 inch lay flat hose (lay flat hose not pictured since I was just testing the spray pattern with garden hose in the yard). If its anywhere near as fast as a bazooka sluice, it will be able to process material as fast as I can shovel it. As you can see, I am keeping the amount of water up top to a minimum so the bottom has enough power to boil out the light stuff. Will post pics + videos when I get more testing time in.

Great job, Astro. I will hook up with you later this week or weekend and let you get a close up look of the quicksand concentrator ebuyc is talking about. We used it last weekend to clean up some cons and it works pretty well.

ebuyc I couldnt find the forum but I think it was astrobouncer who had some pictures of a drop trap sluice he put a fluid bed trap at the end. Maybe he can point to it for us?
GMS did a great job on the E-towers thats why I didnt try, lol

astrobouncer I hope it goes well and will run fast for you! Keep us posted please, this is a fun project that could pan out, lol

astrobouncer:

I really like the concept of this bucket highbanker - compact and uncomplicated.

I may have to build something similar to try out on the flour gold on the NSR, perhaps using the Angus MacKirk grizzly on top of the bucket and a 3/16" punch plate backed up with a slick plate where your grizzly is.

The bucket grizzly doesn't allow you to properly wash material since the 1/2" barbeque grate is flush mounted - I have looked at mine several times and thought about how to improve it - It needs side walls and a way to slow material down at the end in my opinion.  But I admit I have had similar thoughts about using it...

I think I could put a decent pump and a sealed gel battery in one bucket to feed the fluid bed and act as a seat when needed  ;) lol "two bucket method"  lol!!!@*

Something wrong with or funny about the "two bucket method"

No nothing wrong - funny yes - just cracks me up - "two two bucket method" - the voice reminds me of one of my friends and he is a wanna-be comedian for sure - probably has something to do with it  ;)

I actually think the concept is great - but I can't help but laugh when I watch that video!
