The more is the silica, higher is the soda consumption which increases the cost of alumina production. Physical beneficiation techniques are employed to reduce the reactive silica content of bauxite. Based on several investigations it has been made possible to remove ~30% of silica with 92% recovery depending on the characteristics of the ore.

The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (usually of the surface type), bauxite ore is re-moved to a crusher. The crushed ore is then screened and stockpiled, ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing, size classification, and

We can get aluminum from bauxite beneficiation process, and the elements of residues in the process are iron oxide (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%), and insoluble oxidation aluminum (0-20%).. These elements are difficult to completely eradicate from the residue, so it has caused a series of ecological problems.
