This process consumes 2500 to 3000 kWh t 1 of copper produced. The copper is deposited on the cathode and the gases produced at the anode O 2 C 2 are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled hot or cold drawn or even formed into tubes before being sold.
