ADVERTISEMENTS: The metals can be recovered by the microorganisms by two processes: (1) Bioleaching and (2) Bio-Sorption! Soil microorganisms are very closely involved as catalytic agents in many geological processes. These include mineral formation, mineral degradation, sedimentation and geochemical cycling. In recent years, a new discipline of mineral science namely bio-hydrometallurgy .
