We are the local producer and exporter of refractory grade bauxite (Shaft kiln/Rotary kiln/Round kiln).
Our bauxite is from Shanxi Xiaoyi mines. High alumina and low iron. AL2O3 85~90%min, FE2O3 1.5%max; size: 0-1mm;1-3mm;3-5mm;5-8mm;200mesh;325mesh or as buyer's option.
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.
Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
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.

Welding grade bauxite
Welding grade bauxite has tight regulation on presence of sulfur and phosphorus which are detrimental to the weld. When present at high concentrations, they induce porosity and cracking, and at lower concentrations, they adversely affect the impact strength of the weld. And moisture for welding grade bauxite should not exceed 0.5% because the potential for any moisture present withthin the flux to reduce to hydrogent, if exposed to a welding arc, the molten weld pool absorbs the hydrogen and will induce brittleness into the weld.
Application
Welding fluxes are a small but valuable market for calcined bauxite. Techniques for submerged arc welding require the use of a granular flux to shield the molten weld pool rom the atmosphere during the weldâ??s application or pacement. Various proprietary compositions exist and in some cases calcined bauxite is incorportated into these formulations. Calcined bauxite may, in some instances, make up to 25% of the welding flux.

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.
We supply high-quality bauxite ore, essential for aluminum production, cement, and industrial applications. Sourced from reliable mines, our bauxite meets strict quality standards, ensuring optimal composition and performance for various industries.
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.
