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 85OC to 1600C. 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.
