"WORKING BLACK SAND and SULFIDES in GOLD RECOVERY"
Heres How You Do It
Getting upto 90% of your Sulfide Gold out of the Black Sand Concentrates
1,[FOR STARTERS] What you'll need to process Black Sand Concentrates.
one #12 classifier...
one #20 classifier...
two gold pans...
water...
wash tub....
few 5 gallon buckets...
micro sluice or gold wheel...
tumbler andKeene Gravity Bowl...
2, Your first few steps.
Classify your material into several sizes...
Larger than # 12 [nugget size, you can pick'em out]...
Larger than # 20 [micro sluice/gold wheel or you can pan this out, it's really easy]...
Smaller than # 20 [this is for your tumbler]...
3,Put the smaller than #20 concentrates into your tumbler...
Add acidic acid "cider vinegar" or Citric acid "stronger"and tumble over night...
Take concentrates "the tumbled stuff" when done flush brown mud "dissolved iron" with water and add cons using a small scoop into a running KGB BOWL...
Once finished running the KGB, snuffer out the fine Gold...
Take the remaining Black sand "left in the KGB" and mix it with equal amounts of Table salt...
Put the mixed product into an iron skillet...
heat up untill completely dry "do this outside"...
Once really hot and dry, pour the mix into a tub/bucket of cool water...
"DON'T PUT THE IRON SKILLET INTO THE WATER" Just dump the sand/salt "this fractures the attached Gold"...
Collect up the stuff you just dumped into the cool water...
Now run this material thru your KGB gravity bowl...
Snuffer up the visible gold when done...
4, What did I just do, you ask...
You classified your material by size "largest to smallest"...
If you have the necessary equipment "you just eliminated 99% of the panning your concentrates"...
By tumbling the smallest size with vinegar "you just cleaned it up and removed the organics" and much of the iron...
By roasting it, "you fractured the sulfide Gold and attached gold from the black sand"...
5, Is it worth it ???
YOU BET IT IS...
Most of the time there is 4 - 10 times more ulta-fine "Micro Gold" in your Black sand than Visible Gold...
Gold is Gold Reguardless of it's size, oh sure the big stuff is great !!!
But that Fine Gold really can start to add up and do it quickly...
You can go even further and get the really fine invisible micro gold out also. But that gets involved using some basic chemistry
and several more steps and some additional time and expense.
