future of the hydrometallurgical processes in copper ore

  • Treatment of raffinate generated via copper ore

    The hydrometallurgical process to produce Cu consists of three steps bioleaching extraction and electrolysis . During the bioleaching process acidic water is used as the leachate to which Cu is transferred from Cu ore. By extraction using a selective organic extractant Cu is transferred from the leachate to the organic extractant.
