Abstract

Universal reserves of high-grade ores are diminishing at an alarming rate due to the rapid increase in the demand for metals. Biomining is the extraction of specific metals from their ores through biological means, usually microorganism. Biomining is done in two steps often called bioleaching and biooxidation. Bioleaching commonly refers to biomining technology applied to base metals; whereas, biooxidation is normally applied to sulfidic-refractory gold ores and concentrates. Even though it’s a new technique used by the mining enterprise to extract minerals equivalent to copper, uranium, and gold from their ores, however, nowadays, biomining occupies an increasingly primary place among the available mining applied sciences. The biomining methods are affordable, nontoxic, effective, and likewise environment pleasant. Utilizing biotechnology, efficiency of biomining can also be extended with the aid of genetically modified microorganisms.
