Abstract
Biomining is the process of extraction of economically important metals like copper, gold, nickel and uranium by using microorganisms. This process plays a significant role in bioleaching and bio-oxidation. Bioleaching is used in the process of extraction of copper in which the insoluble metal is changed into soluble metal using microorganisms; whereas bio-oxidation is used for the extraction of gold. The high cost, energy demand and pollution of traditional mining techniques have kindled the interest in biomining technology in recent years.
