Aluminium Smelting - The Australian Aluminium Council

A high electric current is passed through pots via the anode. The current flows continuously from the anode (positive) through alumina/cryolite mix to the lining of the pot (negative) and then onto the next pot. Electricity maintains the temperature of the process at about 950°C and enables the alumina to split into aluminium and oxygen.

Hall–Héroult process - Wikipedia

The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process applied at industrial scale happens at 940–980 °C ...
