Beneficiation of bauxite - [email protected]

the bauxite to provide a desired quality of product. 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
