Beneficiation of bauxite ores
For 1 t of metal production, approximately 2 t of alumina is required, which is obtained through processing 5–6 t of bauxite ore. Large amount of power is consumed for smelting of aluminum, which is mostly provided by coal-based power plants. For this, about 8–12 t of coal is needed per ton of aluminum produced.

Bauxite Mining and Alumina Refining
The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3 : The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.
