The concentration of the Bauxite ore into alumina is done by Bayer’s process. Alumina is then refined into pure aluminium metal through the Hall–Héroult electrolytic process. Aluminium is too high in the electrochemical series (reactivity series) to be extracted from its ore using carbon reduction.

Insoluble components of the bauxite are removed by digesting the ore with very hot caustic soda (sodium hydroxide) in the Bayer process. A waste by product of the Bayer process for producing al oxide from the bauxite ore, red mud contains toxic heavy metals and its high alkalinity makes it extremely corrosive and damaging to soil and life forms, presenting a massive problem for disposal.
