In: Conference Bacterial Leaching Schwartz, W. XXV, 26— During the past 10 years biotreatment of refractory gold ores, which contain finely disseminated gold particles associated with sulfide minerals including arsenopyrite, pyrite and pyrrhotite, has been developed to an industrial application and kumwell exothermic welding pdf tank leaching operations are being run in South Africa, Brazil and Australia [5054—56 ]. The procedure is similar to that of dump leaching. The Lead removal process.
