    Copper cathode hydrometallurgical production (L-SX-EW

    The remaining 20% of primary copper production comes from hydrometallurgical processing of mainly copper oxide and chalcocite ores. This copper is recovered by leaching, followed by solvent extraction and Electrowinning. The final product is electrowon cathode copper, which is equal to or often greater in purity than electro-refined copper

    A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting
