Part of an interactive online booklet about copper mining explaining the electrolysis. page 5: Electrolysis ... high purity copper required by industry. Picture 9. ... Under these conditions, copper atoms dissolve from the impure anode to form copper ions.
Extraction of Copper Purification by Electrolysis. High purity copper is needed to make electrical wires. The anode is a block of impure copper. The cathode is a thin piece of pure copper. The electrolyte is copper sulfate. When electricity is passed through the cell. copper is dissolved at the anode by oxidation. and Cu2+ ions go into solution.
