Chinese Calcined Bauxite with Low Price
Introduction of calcined bauxite
Calcined bauxite is one of the principal ore of aluminum.
Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .
Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .this can removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 75% to 90%.
