The application of microbial technology to mineral processing has been reviewed with respect to the bioleaching of metals from minerals, the influence of biotreatment on flotation, the biobene ficiation of nonmetallic minerals, and the biotreatment for mine waste reclamation.The application of microbial technology to mineral processing has shown the advantages of high efficiency, low energy and reagent consumption, low capital and operating costs, and low pollution of the environment.
