Purification copper

Oct 01, 2020

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 Cu 2+ ions go into solution

    The impure copper is then purified by electrolytic purification to 99.99% pure copper while the iron oxide is disposed of as slag. Typically, in this process there is more sulfur dioxide produced by weight than there is copper. Rather than discharge the sulfur dioxide into the air, as was once the practice, the sulfur dioxide is captured and
