copper oxide refining

  • Copper Refining - an overview | ScienceDirect Topics

    Copper is primarily extracted from copper sulfide, first by converting sulfide to oxide (roast) followed by carbothermic reduction However, the product still contains too many impurities and needs refining, which is achieved by electrolysis using impure copper as the anode
