gold processing electrowinning process

Innovations How Hydrometallurgy and the SX/EW Process

The electrowinning of copper requires considerably more electrical energy than does the electrorefining process an average of about 8 MJ/kg for electrowinning vs about MJ/kg for electrorefining In electrowinning the copper must be reduced from the cupric form to metal; whereas in electrorefining the copper is already in metallic form and is merely transported from the anode to the
