In fact microorganisms can be successfully used for the extraction of metals e.g. copper zinc cobalt lead uranium from low grade ores. Mining with microbes is both economical and environmental friendly. The term metal is used to any substance that is hard possessing silvery lusture and is a good conductor of heat and electricity.
