Copper extraction techniques

Pyrometallurgical extraction. The following is a process of copper extraction from chalcopyrite ore into pure metal. While oxide ores can be processed using pyrometallurgical techniques, hydrometallurgical methods are more cost effective. The copper ore is crushed and ground before it is concentrated to between 20 and 40% copper in a flotation ...

Smelting and Refining Operations

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).
