Controlling of the Grade of Bauxite for Aluminum and ...

+

The main ore of aluminum is bauxite, which is a combination of a number of minerals. The typical bauxite grade useable in the Bayer process consists of 50 55 % Al 2 O 3, up to 30% of Fe 2 O 3, and up to % of SiO 2. Bauxite with a concentration of SiO 2 higher than 50% is suitable only for the manufacture of refractories, chemicals, abrasives, and cement. Hence, the commercial value of ...

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. Bauxite residues are then removed, leaving the process liquid, termed "green ...
