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
Please let us know about your health condition. Have you recovered from sepsis? Did you have any serious complications? I am worried about you, my friend. I hope to see you soon in good health.
You need to wear a mask brother i have some more important information for you this one should finally make you rich. When dissolving sulfide sometimes the pgms stay locked in the acids i was watching this other video on how to unlock.the sludlfide and it worked, well kind of i added something. You know what eletrolosis is wel you shock the acid solution with the negative(black) being connected to the iron cathode and the red attached to a piece of copper thick wire will work ( will eat away slowy) and the pgms would accumulate on the copper well this didn't happen for me immediately untile i droppiled in some smb and it started coming to the top like sponge i think this was because it was contaminated with alot of zinc. I dissolve the metals with 50/50 hcl distilled water add 1/2 cup of peroxide when cold heat for 45 minon high add another 3/4 cup not all at once because when hot will over boil.45 min after adding seond dose. After cooled and strained it is ready for smb and eletrolosis. This is literally a cheat code to unlock sulfides. All i ask in return is that you start to wesr protection! Much love brother time to graduate as well as anybody who reads this information, becauseit is meant to be shared !
How are you sir I have learned a lot with your help I actually consider you my teacher I am working on precious metals a problem is bothering me again and again what is the reddish brown color in stannous chloride after dissolving in Aqua Regia. indicates metal don't understand please answer me
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.
Hey there. I hope you okay? Already 4 weeks ago since the last video. May you found already an insane rich gold mine and you busy all the time? My best wishes are with you. Greetings from Indonesia
@@myadventure7069 Oh no! Came here to write the same question. I always check for your videos and had been wondering where you went. I hope your recovery goes well.
Morning can i email you i hâve a problem with my gold precipitate from aqua rega impossible to melt it in microwave and with fire too can you help me please
@@myadventure7069 😥I hope my friend that you are in good health. And that we see you soon, well and in good health.... We missed your beautiful videos a lot.. I am sorry
