The leaching and adsorption behaviour of gold ores

2020-8-28  from the dissociation of the complex is used to leach gold from the ore. 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.
