Key Stage 3

Meaning

Electrolysis is a way to extract metals from minerals when the metal is more reactive than Carbon.

About Extracting Metals by Electrolysis

Metals that are more reactive than Carbon cannot be displaced with Carbon so electrolysis is used to extract them.

Carbon electrodes are used to pass an Electrical Current through the molten mineral. The metal collects at the cathode which carries a negative charge and the pure metal is removed from the electrolysis cell.
