#0183;#32;Copperammonia catalyzed thiosulfate leaching of silver sulfide is by substitution of cupric or cuprous for silver. The cupric reaction is favored over cuprous reaction due to a thermodynamic barrier, even though Cu 2 S and Ag 2 S have similar structures.. Copperammonia leaching with low copper concentrations (1 mM) leaches silver most rapidly for stable cupricammonia complexes

Black Sand Gold Recovery Part 2. Black sand has a specific gravity of from 5 to 11, or 5 to 11 times the weight of water. Gold, on the other hand, has a specific gravity of around 19 and platinum around 21. As you can see, gold and platinum can be two to three times the specific gravity of black sand, and this is why gold or platinum can be
