BBC Bitesize - GCSE Chemistry - Electrolysis -

Purifying copper by electrolysis Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper(II) sulfate.

Purification of Copper - Animated Science

The copper for electrical wiring has to be very pure. The copper we extract from copper ores contains impurities. We can remove these using electrolysis.

AngliaCampus : Purifying metals by electrolysis

Purifying metals by electrolysis: Most metals need to be purified as the presence of impurities affects the properties of the metal, for example they can make impure

copper extraction and purification - chemguide

Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

How can electrolysis be used to purify copper? |

Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure.
