WebThe term bioleaching refers to the conversion of an insoluble metal (usually a metal sulfide, e.g., CuS, NiS, ZnS) into a soluble form (usually the metal sulfate, e.g., CuSO 4, NiSO 4, ZnSO 4 ). As the metal is extracted into water, this process is called bioleaching. Because this process involves oxidation, it may also be termed biooxidation . WebBioleaching. Bioleaching (or biomining) is a process in mining and biohydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from a low-grade ore with the help of microorganisms.
