Extraction of Aluminium (Aluminium Ore) - Hall-Heroults ...

In this method of production of aluminium for every 1 kg of Al produced, approximately 0.5 Kg of carbon anode is burnt. Aluminium ions are created at the adverse cathode from the aluminium oxide and then sink down because they are heavier than the cryolite solution. Then, the liquid shape of the aluminium that has sunk to the bottom.
