Home Products use of microbes in mineral beneficiation process

Environmental Biotechnology of Mineral ProcessingSpringerLink

Minerals occur in nature in an unrefined form, that is, in a state which is obviously of no industrial use. Processing often includes ore crushing, while refining is usually achieved by smelting the ore at high temperature-i.e. by an extremely energy intensive process. The role of bacteria in copper mining operations.
