Biomining is a technique of extracting metals from ores and other solid materials typically using Some microbes can use stable metals such as iron, copper, zinc, and gold as well as unstable atoms such as uranium and thorium. The development of industrial mineral processing using microorganisms has been
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.
