Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).calcined bauxite is typically calssified according to its intended commercial application,such as abrasive, cement, chemical, metallurgical, and refractory as raw material for use in high alumina and super duty refractory bricks and shapes, plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.
