It is expensive, largely because of the amount of electricity required in the extraction process. Aluminium oxide is called bauxite. Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. Aluminium oxide does not dissolve in water, but it does dissolve in molten cryolite.
That's why chloride added to Aluminium oxide during the extraction of aluminium.
Hope it will help you.
