• Why the Extraction of Copper from Chalcopyrite is so ...

    The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silie, carbonate or sulphate ores. So, extraction of Copper from it becomes very difficult it is a lengthy process because(i) It contains many impurities in such a high amount that the percentage of Copper in it becomes ...

  • Electrowinning Copper Chemistry Tutorial

    Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably). Copper ores are usually copper oxides, copper sulfides or copper .

    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). All the studied ...
