• Innovations in Copper: Mining Extraction: Producing ...

    Prior to the development of the solvent extractionelectrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copperbearing solution with scrap iron. Impure metallic copper was precipitated on the iron surface while an ...

    Principles of Metal Extraction: Metals are found in the combined state in ores where they exist as positive ions. During the extraction of metals, the metallic ions must first be reduced to the corresponding metal atoms. This reduction process can be done electrolytically or by thermal or chemical methods.

    Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
