Three crushing plants are used to reduce the size of bauxite for use in alumina factory. The ore is hauled to these crushing plants by truck from the mine. In the first step the ore is moved to a primary screen with two levels and are divided into three parts: (i) <20 mm (ii) between 20 mm and 10 cm and (iii) >10 cm. The ore with the size …

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.
