Calcination is a process of heating, hence calcined bauxite is obtained by heating the high grade ore of the bauxite. Heating further removes the moisture content from the ore and thus results in the increase of the alumina content.
Bauxite, an aluminium ore, is the world’s main source of aluminium. It consists mostly of the minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite.
Bentonite is highly used plastic clay and is an absolute gem of a product to be manufactured in terms of industrial purposes. It is of great commercial importance with inherent bleaching properties. It is these bleaching properties that make it useful and different from other materials. Bentonite because of it having such unique bleaching qualities has been named as Bleaching clay.
Excellent plasticity, higher bonding strength, high shear and strength, low level of permeability and compressibility and many such qualities in short make it all the while important. It also has a varied amount of uses in well-known industries like rubber, paper and cosmetic industries.
