    Jul 07, 2013 When microorganisms are employed to extract minerals from the tailings and ores, the process is called biomining/ microbial mining. Metals are first solubilised which is leaching carried out by microbes in biochemical waste and then separated by sedimentation. It is not very costly and highly useful for river and low grade ores

    Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of
