Beneficiation of bauxite

Beneficiation of bauxite

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, eg 2Na2O2Al20;,3Si022 H20 This salt is eliminated from the process along with the insoluble iron and
