    2001-5-28 · Copper is a very unreactive metalit s below even hydrogen in the reactivity series. This means it won t even react with water. For this reason copper is obtained very easily from its ore by reduction with carbon.. However this copper isn t pure enough for use in electrical conductors. The purer the copper is the better it will conduct. Electrolysis is used to obtain very pure copper.
