What Is Electrorefining? (with picture)

Most of the world's copper is produced through electrorefining, which removes silver, gold, and platinum metals as well as nickel. The precious metals that are separated can be recovered within the sludge that collects outside the copper electrode. Copper is high in electrical and thermal conductivity and is relatively easy to cast, extrude, and roll.
