Cyclone Circuit In Copper Mine – Hydrocyclone Separator

All ores, including the oxides aretreated through flotation, with the mixed andsulphide ore float tailings being thickened anddischarged to the tailings storage facilities, andthe oxide float tailings being leached, followed by solid liquid separation in a CCD circuit.Copper recovery from solution is byclarification and conventional SX and EW.Kansanshi thus produces copper in the form ofboth cathode and concentrate.
