The process of aluminium extraction by electrolysis. Extended tier only. Bauxite is first purified to produce aluminium oxide, Al 2 O 3. Aluminium oxide is then dissolved in molten cryolite. This is because aluminium oxide has a melting point of over 2000 °C which would use a lot of energy and be very expensive.

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 the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.

Aluminium Extraction. Al is the most abundant metal in the Earth’s crust. It is a very important metal to be extracted from earth crust because: Resistant to corrosion due to the formation of a protective layer of aluminium oxide.

· Abstract. The industrial production of aluminium is based, since the end of the nineteenth century, on the electrolysis process. Aluminium is in fact not present in the nature in its pure metallic form but as an oxide called Alumina ( Al 2 O 3) and an adapted processing (electrolysis) is to be used to extract the metal.
