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.

Outotec offers complete cyanide leaching plants irrespective of the material quality. Free-milling gold materials are cyanide leachable and so are the refractory gold materials after suitable pre-treatment. Possible pre-treatment methods such as pressure oxidation, bio-oxidation, roasting, and ultra-fine grinding are also included in our offering.
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding .
