extracting gold from sulphide ores

 

Bioleaching Refractory Gold Ore

Bacterial extraction of gold from sulfide bearing ores has been studied by many investigators. If gold occurs finely disseminated within the sulfide ore matrix such as in pyrite, arsenopyrite and pyrrhotite, the leachant can notrate into the inside of solid ore in order to leach the enclosed submicron size gold particles. For their liberation, the sulfide bearing ore is subjected to
