Extraction of Aluminium (Aluminium Ore) Hall-Heroults

1/8/2016· 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 carbon and graphite rods is used.

Extraction of Aluminium Chemistry, Class 12, General

5/15/2020· At cathode : Al3+ (melt) + 3e¯ ——> Al (l) At anode : C (s) + O2- (melt) ——>CO (g) + 2e¯. Therefore, aluminium is liberated at the cathode and gets collected at the bottom of tank, from where it is removed periodically. The oxygen evolved at the anode combines with the carbon of the anode to produce carbon monoxide.
