Bioleaching Refractory Gold Ore

19 · If gold occurs finely disseminated within the sulfide ore matrix such as in pyrite, arsenopyrite and pyrrhotite, the leachant can not penetrate 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 preoxidation by bacterial leaching.
