  • Solvometallurgical process for extraction of copper from

    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).
