  Solvometallurgical process for extraction of copper from chalcopyrite ...

  20191213 · 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 ethylene …

  A conceptual process for copper extraction from …

  201771 · A novel integrated alkaline process for the extraction of copper from chalcopyrite has been proposed and the chemistry of the main steps in the process including reagent recirculation has been demonstrated. At ambient temperatures, copper extractions of up to 52% are achievable after 580 h in solutions of glycine and air as oxidant.
