Many litotrophic and organotrophic microorganisms are capable of metal recovery. Bacteria and fungi are capable of bioleaching, which is the conversion of solid compounds into soluble and extractable compounds. Platinum group metals (PGMs), rare earth metals (REEs) and different heavy metals such as Pt, Fe, and Zn, etc., can be absorbed by naturally occurring microbes rather than high metallurgical technologies because they use more energy and have a higher carbon footprint when compared to biotechnological and microbial approaches. Biomining and bioremediation are two widely employed technologies in biometallurgy involving the extraction, recovery and immobilization of metals, radionuclides from sites. This overview discusses the various microbe-metal interactions, biosorption, bioleaching, signficance of sourcing metals with the aid of microbes and biological methods given its low energy usage and minimal waste generated.
