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.

Kaolin: Kaolin uses are multiple and diverse. Kaolin are used as functional filler, extender, ceramic raw material and pigment because of its whiteness and fine particle size. Kaolin also hold importance as raw material in refractory applications, concrete, rubber and fiber glass manufacturing. We, as a Kaolin Exporter welcome any size of international orders from Middle East and other countries. Applications: Paper: Kaolin used as a coating pigment and as a filler to replace fiber. It possesses desirable optical properties. Concrete: Kaolin helps to improve strength and durability of concrete. When added to concrete mix, reacts with free lime released during cement hydration to produce additional cementitious material, resulting in an improved high performance concrete. Plastics : Kaolin is widely used as filler in the plastics industry because of its inert chemical nature and its unique size, shape and structure. Agriculture : It is used as a carrier and diluent in fertilizers, pesticides and related products. It is suitable as carrier because it aides the retention of the formulations on the plant. Rubber : It is commonly used as functional filler in rubber applications. While Kaolin improves overall performance for Rubber in general, different types of white pigment play specific roles in rubber application. Paint : Kaolin used as an extender in paints. It reduces the amount of expensive pigment such as Titanium Dioxide. It assists with desirable rheological properties that help maintain proper dispersion and provide bulk to the product. Ceramic : Kaolin improves whiteness and brightness of ceramic body. Good plasticity, good shrinkage, low water absorption and casting rate are also very important properties of kaolin.

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.

Ball Clay: A member of kaolinite family, Ball Clay is renowned for its plasticity and green strength. They consists varying proportions of kaolinite, mica and quartz, with small amounts of organic matter and other minerals, and are commercially values because they increase the workability and strength of various ceramic bodies and have white or near white firing characteristics. Ball clay is processed to minimize the levels of coarse particles. This enhances better workability and higher strength. Applications : It forms a major part of many ceramic applications, including sanitary ware, tiles, table wares and to an increasing extent non-ceramic applications like functional fillers and advanced application for example technical ceramics.

China Clay: China Clay is a clay mineral with the chemical composition AlSiO3O5(OH)3. It is layered silicate mineral. It is soft earthy, usually white in color, produced by the chemical weathering of Aluminium Silicate mineral like Feldspar. Commercial grades of China Clay are supplied and transported as dry powder form, semi dry noodle form or as slurry. Applications: - It is used in Cer/bamics for body & glazing of Tiles and Sanitary Wares. - In paper it is used as filler. It is also used for paper coating purpose. - It is used in paint also to extend Titanium Dioxide (TiO2) and modify gloss level. - It is used in rubber to enhance reinforcement properties.

We are exporter of 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) 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.

Natural Gypsum: Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India. Applications: Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as: - a retarder for Portland cement - a fertilizer or soil conditioner - mineral filler - oxidizing agent in glass manufacture or other industrial applications. Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement. Imported Gypsum from Iran: Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.
