Copper is a very unreactive metal - its below even hydrogen in the reactivity series. This means it wont even react with water. For this reason, copper is obtained very easily from its ore by reduction with carbon.. However, this copper isnt 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.
