The Leaching And Adsorption Behaviour Of Gold Ores

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 cyanides fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.

Gold Cyanide Leaching Process Xinhai

Apr 12, 2019 Gold is a kind of inactive metal, which can cause complexation reaction with cyanogen CN- under the action of oxygen in the cyanide leaching process, and then results in Au CN 2-. Therefore, cyanide agent dosage is one of the key factors determining the gold dissolution. In general, the pulp should contain a certain amount of unbonded ...
