    Impurity control and removal in copper tankhouse

    When copper dissolves during electrorefining in a copper tankhouse these impurities are continuously released from the anodes either as insoluble phases slimes which fall to the bottom of the cell or as dissolved species in the electrolyte the transfer of which to the cathode must be inhibited.
