Purifying Copper by Electrolysis - Everything2

May 28, 2001 · Copper is a very unreactive metal - it'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.
