Biomining

Abstract: Biomining is the extraction of specific metals from their ores through biological means usually bacteria. Although it is a new technique used by the mining industry to extract minerals such as copper, uranium and gold from their ores but nowadays biomining occupies an increasingly important place among the available mining technologies.
