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 removes moisture there by increasing the alumina content. compared to an alumina content of about 57%to 58%in raw bauxite, calcined bauxite has an alumina content of 84%to88%.the heating is carried out in rotary kilns.

Bauxite is a sedimentary rock composed primarily of aluminum hydroxide minerals, such as gibbsite, boehmite, and diaspore. It is the primary source of aluminum ore and is typically found in tropical and subtropical regions. Bauxite is most commonly used in the production of alumina (aluminum oxide), which is then refined to produce aluminum metal. Aluminum derived from bauxite is widely used in industries such as aerospace, construction, packaging, and transportation due to its lightweight, strength, and corrosion resistance.
Bauxite stands as the fundamental source of aluminum, undergoing a refining process to yield alumina, which subsequently undergoes smelting to manufacture aluminum. This versatile metal plays an integral role in diverse sectors such as packaging, transportation, construction, and the electrical industry. Our company takes immense pride in its role as the leading global exporter of bauxite, underscoring our unmatched prowess in facilitating the supply chain for this essential commodity across various industries.

Bauxite ore
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (Y-AlO(OH)) and diaspore (�±-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).[1] Bauxite appears dull in luster and is reddish-brown, white, or tan.Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis.[9] Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory.

Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperatures (from 850 to 1600) in the rotary kiln. This 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 84% to 88%. Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.
