Silver & Gold Cyanide Leaching of Copper Ore

2021-1-19 · Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2-, Cu(CN)3=, and Cu(CN)4=-, although Cu(CN)3= is considered the most probable of these. According to leach scientists, the complex having an empirical formula KCu(CN)2, is not a solvent for gold and
