Extraction of Aluminium (Aluminium Ore) - Hall

The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering of the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with the lining of
