Title: 10 ppm = how much gold per ton?
Post by: NickMarch on December 03, 2009, 05:47:49 AM

Thanks for any help!

That would be 10 grams per tonne = about 1/3 of an ounce per tonne = 9.09 grams per ton (for the US folks) = .29 of an ounce per ton

the formula to use for down and dirty converstion is:
1 ppm = one gram in one tonne of sample
A tonne = 2200 pounds = 1000 kilos
so a fast one on the calculator is:

ppm divided by 2200 x 2000 = grams per ton
grams divided by 31.1 = troy ounces

A walk through some measurement systems:

A metric ton (tonne) is about 2200 lbs. It is 1000 kilograms, and therefore 1 million grams. Love the metric system, as it makes things so easy.

If you have aggregate that tests 10 ppm, then there are 10 grams per ton. Not bad.

Cheers

EDIT, GMS posted his just as I did mine...

Another way of looking at it is there's 1,000,000g (1 million) in a tonne so 10 ppm (parts per million) is 10g

10 grams of gold/tonne.....is this a good amount per tonne...it sounds pretty good to me   <-yahoo_>

Was this the assayed value of this sandy loam?
If so do you know what form the gold is in? is it free flakes of gold or still locked in the sand and loam?

Nice find.  One gram per tonne is great!  10 is to good to be true in my world.   Estamating gold at $40.00 per gram and 10grams per tonne that is $400.00 per tonne.  I have a very small system and run a load every 5-6 minutes.  $4000.00 per hour, I'd be OK with that. {cool^sign}

  How many bank yards are there?  Wheres the nearest water source?  How much water is available?  Is there enough room for ponds?   Is there clay in the matrix of the product?(What kind of washplant do you have?)

Once the product is washed I think a jig system may be the recovery system to consider.  If it is in sand, it is probably small and could be flat.  So low velocity recovery is what I would consider.

Just thought I would put my 2 bits in. lol

Look up the word "eluvium".  Farncombe Hill's BRIARPATCH is quite noteworthy.

here is a great Link to an online conversion table, this will do everything for you, just input the value and measurement and the conversion desired and it will do the math for ya.

Units converter for dimensionless (http://www.calculator.org/property.aspx?name=dimensionless)

I use it all the time

IS THE LOT STILL IN A NATURAL STATE OR HAS IT BEEN PARTIALY DEVLOPED.  test, test, test

just got an assay back at 15.76 PPM on my tailings its so fine i cant catch it ? have thousands of yards of it ?

Hi.terryr.That is almost 1/2 ounce per ton and a ton is not much.Best look at a better capture method.You are on some good gold.Luck Mcbain.

Yes he can!  I have stood right next to  "johnedoe" as he worked and I've seen him catch Talcum Powder sized Gold hour after hour!

I didn't do as well.

Thank you for the vote of confidence Joe.

So anyway Terryr, Drop me a PM and we can talk about this.
And by the way..... I do this mechanically no nasty chemicals or mercury.......

The last time Terry R visited us was the third week of November in 2018.

Maybe he learned how to catch that tiny Gold and is now retired to some tropic island he now owns.

I hope that the report actually read PPM and not PPB (as in Billion).

All the Best, Terry R!   <-dont~know->

Yeah I saw when his last appearance was...
I just figured I'd put it out there just in case..... You never know.
And like you even though I would like to help him out I hope he has got it figured and is sipping one of those nice cool tropical beverages on some warm sandy beach ....... ;D

Welcome back Terryr.
I would like to see some of those tailings.

Terry.
I sent you a PM with my contact info.
