Microbial Leaching (Bioleaching, Biomining .

Gold and Silver Leaching Today's microbial leaching of refractory precious metal ores to enhancegold and silver recovery is one of the most promising applications. Gold is obtained through bioleaching of arsenopyrite/pyrite ore and its cyanidation process. Silver is more readily solubilized than gold during microbial leaching of iron sulfide.
