SO 2 Electrowinning in Copper Hydrometallurgy for Energy ...

Jan 07, 2014  Conventional copper electrowinning involves the decomposition of water at the anode and has a cell potential of approximately 2 V. If the anode reaction is changed to involve the oxidation of sulfur dioxide the cell voltage can be cut almost in half and this change can dramatically affect the overall energy consumption of a hydrometallurgical process. As well as saving energy, this reaction ...
