Biomineralization of metalcontaining ores and concentrates

Biomineralization of metalcontaining ores and concentrates

Jan 01, 2003 Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be readily recovered from solution.
