Abstract. 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 …

The process isolates the impurities that concentrate in the molten zones, leaving the portions behind them somewhat more pure. This process is repeated until impurities are moved to the end of the rod and cut off, resulting in an almost completely pure metal rod.

If pyrometallurgy is unavailable, we recommend either the chemical leaching process or the bioleaching process at 10 % PD. As with the combined process for copper and gold recovery, bioleaching of copper at 1 % PD leads to significantly greater environmental impact in comparison to the recommended processes. 4.
