Bauxite Ore Beneficiation

out the ore and it is often necessary to beneficiate 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

    Advances In Beneficiation Of Lowgrade Bauxite Springerlink

    Abstract. Bauxite is the major alumina Al 2 O 3 bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50 Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. The alumina-silica and alumina-ferrite complexes are the foremost impurities present in the low-grade bauxite
