Might have some ultra fine gold lock-up in the partially oxidized sulfides (brown sands), which are being panned off to tailings. In my quartz ore, if I want to concentrate, I do so at minus 40 - 50 mesh, and then panning down to the brown sands. Then roast off remaining sulfides and then grind them to minus 200 mesh before leaching. Each ore has it's best method though.

I’ve also heard as ‘another’ method to roast black sand concentrates under high heat, then submerge them in (ice) cold water help release (crack out) the gold as well. But this method is more for alluvial gold concentrates.

I've tried it a couple times long ago, but didn't see anything liberated. Of course, it all depends on the placer deposit. It would apply to particulate gold which is coated with manganese mineral, hematite, or possibly magnetite -- the theory being that the gold expands with the heat and the mineral shatters with the quench. My post refers to ultra-fine particulate gold, gold films and gold telluride deposited on the sulfide lattice planes. Takes a lot of it to make Something, An eventual source of Placer "gold dust." ​@@royjohnson465

Brilliant idea with the black sand sir! I will be utilizing that to increase production. Thank You😁

health & wealth for you

But what if you check the stones with a metal detector first, so as not to waste time on chemistry?

Tell me, how do you release gold after urea?

Can you use baking soda to also neutralize the nitric acid?

Hello have you ever tried leaching with thiosulphate

😊

Dear sir, if gold is in powder ( DUST ) form, can it be dissolved in nitric acid?

To dissolve gold you need chlorine . Aqua regia produces chlorine and dissolves gold.

Hi there, What is your ratio for KNO3:H2O solution ? Have a nice day.

I don't understand the chemistry behind this method of obtaining aqua regia, did I miss a lesson on nitric acid? I have seen references to sodium nitrate as well.

​@@myadventure7069thanks, I have seen many recipes for leaching, with oxidizers like perchlorate or peroxide with HCl and even NaCl for free chlorine. I am rereading De Re Metallica chapter X just to get a handle on it.
