Furthermore, processing of ore concentration in the past was only applicable to copper sulphide although copper ore is a mixture of copper sulphide and copper oxide (pers, Environmental coordinator for Konkola Copper Mines). Thus, copper oxide was being lost

  • Chromite Wikipedia

    Chromite mining is necessary when it comes to the production of economic commodities. As a result of leaching of soils and the explicit discharge from industrial activities, weathering of rocks that contain chromium will enter the water column. The route of chromium uptake in plants is still ambiguous, but because it is a nonessential element, chromium will not have a distinct mechanism for
