A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20,.3Si02.2 H20. This salt is eliminated from the process along with the insoluble iron and

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.
