A new approach for ecaluating wastes: Bioleaching

Abstract

Bioleaching is a biological process where metals and microorganisms have been interaction. At this processes microorganisms prove recovery of metals by dissolving insoluble forms of them. However this biological solubilization is often used at recovering metals from ore mining, wastes have also considerable economic importance at metal gaining for their cheap raw material. At the recent years, it has been reported that important amount of aluminum, zinc, nickel and copper can be extracted from different kind of municipal and industrial wastes.
