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 bauxite contained 48.8 % Al 2 O 3, of which 37 % was present as boehmite, 9.1 % SiO 2, all in kaolini te. The kinetic test was carried out at 100 o C in a liquor that contained 149.5 g/L ...

The project is being developed in two phases, with the first phase involving an investment of $1.4bn. The $4bn second phase involves the construction of an alumina refinery. The first phase is expected to produce 12 million tons per annum (Mtpa) of export-quality bauxite ore, starting from mid-2019. It is estimated to have a mine life of 20 years.

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 processing equipment. As we know, bauxite ore is very hard, so it takes a longer time for crushing.
