Electrorefining - Purifying Copper in Industry - Activity

Copper is a very good conductor of electricity and is used for electrical wiring and cables. However, even small amounts of impurities can reduce its conductivity noticeably. The metal must be 99.99% pure to be used in this way. To ensure this level of purity, copper has to be purified by electrolysis after it has been extracted from its ore.
