Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). 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 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application.
We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices.
Applications of Calcined Bauxite:
Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%.
Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.
Calcination is a process of heating, hence calcined bauxite is obtained by heating the high grade ore of the bauxite. Heating further removes the moisture content from the ore and thus results in the increase of the alumina content.
Bauxite, an aluminium ore, is the world’s main source of aluminium. It consists mostly of the minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite.
Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH)
Bauxite is used in a lot of industries like the chemical industry, refractory, abrasive, cement, steel, and petrol industry amongst others. In chemical, bauxite along with alumina is used in the manufacturing of aluminium chemicals. In refractory, it is used as a raw material for making several products.
Calcined Bauxite is produced by sintering highalumina bauxite ore at high temperatures 16001800C to remove moisture and volatile impurities It has high alumina content excellent thermal stability low iron and low alkali Widely used in refractory industry abrasives steel plants cement and foundry applications

The composition of bauxite consists mainly of aluminium hydroxide minerals, such as gibbsite Al(OH)3 along with various impurities such as iron oxides, silica, and titanium. The colour of bauxite can range from grey to brown, yellowish-brown, or reddish-brown, depending on the presence of impurities. Bauxite is a crucial raw material for the production of aluminium, which is widely used in various industries such as transportation, construction, packaging, electrical appliances, and aerospace. Aluminium is valued for its lightweight, corrosion resistance, high conductivity, and recyclability. Bauxite mining and aluminium production have significant economic impacts in countries with abundant reserves.
