Gold in nature, as opposed to the gold in a laboratory, has varying degrees of resistance to being dissolved by a leach. In nature it is mixed with base metals, such as iron, copper, zinc, tin, and any number of other metals. Sometimes when a leach has dissolved 1/2 the gold, it

Silver amp; Gold Cyanide Leaching of Copper Ore

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.

The stepwise dissociation of cyanide from copper cyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.
