Copper Mining and Extraction: Sulfide Ores

Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about 1.3V and so the process is safe. What happens in electrolysis? Under these conditions, copper atoms dissolve from the impure anode to form copper ions.
