Extracting Metals by Electrolysis
Key Stage 3
Meaning
A 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. |
