Hi guys,

In the textbook for OCR GCSE Chemistry, it says we use electrolysis to extract aluminium from its ore - bauxite.

Bauxite contains aluminium oxide doesn’t it ? Bauxite is just the combination of rock and the Al2O3 within this rock, so surely electrolysis isn’t seperating the metal from its ore, instead it’s separating the metal from the metal compound, which was apart of the ore ?

This is really confusing me.

Any help would be greatly appreciated.

Lewis

I do Aqa but...
Yes.
Bauxite is extracted and it is separated from the rock and the aluminium oxide.
The oxide is then melted to become molten using cryolite
This is then separated
