RK Bauxite
Bauxite is one of the principal ore of aluminum.
Bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .
Bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 850C to 1600C) .this can removes moisture thereby increasing the alumina content.
CH Refractories manufactured bauxite is rotary kiln bauxite, 100% without recycling raw material, we guarantee full content of Al2O3. There are two different levels bauxite with yellow and darker color
