  • Copper, Lead and Zinc Smelting and Refining

    When sufficient copper has been cemented out, the copperrich iron is put into the smelter together with the ore concentrates for copper recovery via the pyrometallurgical route. In the SXEW process, the pregnant leach solution (PLS) is concentrated by solvent extraction, which extracts copper but not impurity metals (iron and other impurities).
