Answer:
The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis. ... positively charged aluminium ions gain electrons from the cathode, and form molten aluminium. oxide ions lose electrons at the anode, and form oxygen molecules.
Cryolite lowers the melting point of the ore and make it more conductive in nature so as to carry out electrolysis of the ore in Hall- Heroult process.
