Abstract
Cyanide leaching of gold from refractory sulphide concentrates and ore with preliminary bacterial oxidation or in FeCl3 solution has been researched. It is shown, that oxidation in FeCl3 solution has advantage in speed and degree of iron pyrite oxidation, allowing to attain more than 99 % of gold leaching.
