Biohydrometallurgy is a/an

Biohydrometallurgy may be defined as that branch of biotechnology dealing with the study and application of the economic potential of the interactions between the microbial world and the mineral kingdom. Biohydrometallurgy is used to perform processes involving metals, for example, microbial mining, oil recovery, bioleaching, water-treatment and others. Biohydrometallurgy is mainly used to recover certain metals from sulfide ores. It is usually utilized when conventional mining procedures are too expensive or ineffective in recovering a metal such as copper, gold, lead, nickel and zinc.
