Bioleaching definition chemistry
WebApr 8, 2024 · Bioleaching has more potential for using industrial solid waste due to its mild reaction conditions, feedstock adaptability and high target selectivity (Lv et al. 2024a). The bioleaching results show that: (1) The suitable microorganisms can achieve high leaching efficiency while accomplishing the target elements. 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 .
