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 removes moisture thereby increasing the alumina content.

It has been verified that China has reserves of bauxite totaling 1000 million tons, half of which can be sintered to bauxite clinkers with >80% A1203 content. Chinese bauxite reserves are mainly distributed in the provinces of Shansi, Henan and Guizhou. The total annual output of bauxite clinker is ...

Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 1800 degree Celsius in the rotary kiln. In this calcination process the high refractory mineral phases corundum and mullite are formed.

The refractories industry is in general dependent on China for raw materials, for example 95% of refractory bauxite production is controlled by China. On the other hand, China changed its policy, and now discourages the export of raw materials.

With its high aluminium content, it is the only ore used for commercial aluminium production. This makes the raw material an indispensable mineral in metallurgy, but also in the refractory industry. Whether for the refractory industry or metallurgy we offer raw bauxite in .
