Calcined Bauxite: 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. Minimum Order Quantity : 1 Containers
Features Of Calcined Bauxite 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. Applications Abrasives Refractories Road surfacing
Calcined Bauxite is obtained by calcining (heating in a Kiln) superior grade Bauxite at high temperatures (8500C to 16000C), this process removes the crystalline moisture leading to a higher 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 %. Calcined Bauxite is used as raw material for manufacturing fused alumina and high alumina refractories. Ashapura produces Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc.; we are committed to provide consistency in quality and availability of product at extremely competitive prices.

Calcined bauxite has traditionally been the most commonly used aggregate material used for High Friction Surfacing.The inherent nature of Calcined Bauxite resists shear stresses that lead to polishing of the road surface. Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.Calcined Bauxite has been found to exhibit characteristics far superior to alternative road surface aggregates.
As we all know, China is the world's leading supplier of bauxite, producing over three million tons per year for refractory, abrasive, and welding applications. Calcined bauxite is made of excellent bauxite ores, fired in a kiln to impart its superior abrasive qualities, hardness, and long-term frictional resistance. This materials are in stable index, homogeneous structure and excellent high-temperature performance. Its high alumina and low iron make calcined bauxite be the ideal raw material in refractory and abrasive products.

Raw Bauxite: 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). We are a major Raw Bauxite Exporter based in Maharashtra (India) and catering to the diverse demands of several middle and eastern Asian countries. About Raw Bauxite: The processing of Raw Bauxite is done at a number of alumina refineries in the world. Bauxite can be processed at a low-temperature autoclave digestion (145 oC to 155 oC). Raw Bauxite can be used also for sweetening stage and for non-autoclave digestion in agitators (105 oC). About 85% of bauxite mined worldwide is used to produce alumina for refining into Aluminium metal and the balance 15% is processed and value added to make its way to other uses like refractory, chemical, cement, abrasives, etc. Aluminium is possibly the most versatile product with applications in almost every industry. Since Bauxite is the primary source for Aluminium there will always be an ongoing promising demand for the same. Application & Uses of Bauxite: Raw Bauxite is successfully used for metallurgical grade alumina production besides applications in the cement industry, alumina chemical, steel, alum, energy industries, flame-retardants, etc. Bauxite is used in : - Aluminium - Cement - Chemical - Blast Furnaces - Iron/Steel Ladles, etc. Advantages of Artha Bauxite: Artha Mineral Resources has good sources for Gibbsitic Bauxite which requires low digestion temperature (145 oC -155 oC) making it more economical to process. Mines are also in close proximity to all-weather ports which makes it very convenient and cost effective to ship this material.
Ashapura is a leading global supplier of Bauxite and Aluminous Laterite. Bauxite is the principal ore which is used in making Aluminium metal.
