Aluminum Extraction - an overview ScienceDirect
In the electrolytic extraction of aluminium, the anodic process is the discharge (or oxidation) of the oxide ion, O 2−. The net process is the decomposition of the feed alumina, Al 2 O 3, into aluminium metal and oxygen, which in turn reacts with the carbon (anode) to produce CO 2 at elevated working temperatures (e.g. 900 °C). The process does not change the composition of the electrolyte.

Aluminium extraction - IGCSE Chemistry Revision
2013-1-7 Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. Instead, it is dissolved in molten cryolite - an aluminium compound with a lower melting point than aluminium oxide. The use of cryolite reduces some of the energy costs involved in extracting aluminium.

Explain briefly the extraction of aluminium from bauxite.
The extraction of the metal from bauxite involves the three main steps. Concentration of Bauxite ( A l 2 O 3 . 2 H 2 O ) Concentration of ore is done by leaching which helps in removing impurities like F e 2 O 3 , S i O 2 , etc. Bauxite is treated with N a O H to form sodium aluminate which on further reaction with C O 2 gives pure Alumina.
