Bauxite Powder 

Calcined bauxite is considered as one of the major ore of aluminum. Offered calcined bauxite powder is formed by calcining (heating) top grade bauxite at excessive temperature which ranges between 850℃ to 1600℃. As moisture gets eliminated therefore, it increases the alumina content. Further, calcined bauxite consists of 84% to 88% of alumina, as equated to 57% to 58% in raw bauxite. The entire operation is executed with help of rotary kilns.


Calcined bauxite is categorized according to various industries such as refractory, cement, metallurgical and chemical. These are used as raw materials in refractory bricks which are of various shapes. As these are rich in alumina it is also used in plastics, gun mixes, castable refratory, ramming mixes and abrasive grains.
