SUMMARYEXAMPLES OF CURRENT INDUSTRIAL BIOLEACHING OPERATIONSBACKGROUNDCHEMISTRY OF BIOLEACHINGMICROBIOLOGY OF BIOLEACHINGLEACHING METHODCOSTSRESEARCHCONCLUSIONSBioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached.An associated process is
