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 silver...
