Solvometallurgical Process For Extraction Of Copper From

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.
