Description:
The industry grow steadily based soundly on new and expanding markets created largely by its own study of the properties of aluminium and of the avenues for economical consumption of this new metal. With this growth in manufacture came a decrease in cost, which was largely passed onto customers, even reducing the price 33 cents per kilograms. The price has gradually increased and was $ 1.58 per kilogram in 1980, reflecting inflation and sharp increases in electrical costs. Aluminium is the major nonferrous metal. Residual rocks, in which the alumina trihydate and monohydrate minerals gibbsite, boehmite, and diaspore predominate are classified as bauxites. Other residual minerals are developed in the unique type of rock weathering which produce bauxites, and these minerals kaolinite, halloysite, goethite, hematite, magnetite, anatase, quartz, and some phosphatic and manganiferous minerals may from the lesser constituents of bauxites. Since bauxites have formed from a variety of rock types, minor quantities of residual minerals resistant to weathering. Kaolinite is the chief clay mineral in older bauxites. Thick residual laolinic clays sometimes envelope and usually lie immediately under bauxites. These residual kaolinic clays become more quartzose and halloysitic at depth near the weathered rock contact. Halloysite is rare in older bauxites, but it is a common constituent of younger bauxites and with quartz is usually the main constituent of the residual clays underlying younger bauxites. Some alumina hydrates and hydrour Aluminium silicates are produced also from the breakdown of amphiboles and pyroxenes in igneous, volcanic and melamorphic rocks. Although certain almost pure calcareous rocks from bauxite no bauxite has been found which is known to be derived from coarse high silica or ultra basic rocks. There is very good scope for manufacture of calcined bauxite.

Description:
Calcined bauxite is an important raw material for two main products, refractories and abrasives. Smaller volumes are consumed in other applications including proppant, welding fluxes and antiskid surface. While the process of calcining bauxite for each of these applications is fundamentally the same (i.e. it involve the same basic burning process), the physical and chemical characteristic of each grade vary. Calcined bauxite is classified by the major end use – abrasive and refractories. India currently imports 40–60% (about 1000 tpa) of its calcined bauxite from China. Spurred by expansion of domestic steel production, a scarcity of acceptable quality of bauxite from China and raising import cost, drives are now underway in India to produce high grade bauxite from domestic bauxite sources. At present, India is very minor producer of non – metallurgical bauxite, despite having occurrence of high grade bauxite in west coast and central India. This is attributed to limited effort to test high grade bauxite occurrence in region outside the main bauxite producing area around Gujarat. The product has good demand growth, so there is good scope for new entrepreneurs.

Description:
Calcined bauxite is an important raw material for two main markets: refractories and abrasives. Smaller volumes are consumed in other applications including proppants, welding fluxes, and antiskid surfaces. While the process of calcining bauxite for each of these applications is fundamentally the same. Calcined bauxite is in pure form and in different particle size. Calcined bauxite is widely used in various industries such as refractories, steel plants and so on. Calcined bauxite is one of the chief sources of aluminum. The most important use of bauxite is in metallurgical industry i.e., manufacturing of aluminium. But, it has a few non metallurgical uses also. In most of the uses, however, the products are based on an intermediate product namely, alumina which is made directly from bauxite. The important uses are: Aluminium metal, Semi-fabricated products or semis, Aluminium alloys, Reinforced aluminium composites, Petroleum refining and fertilizer manufacture, Aluminous cement, Proppant in oil wells and Ball mill grinder etc. There is very wide scope and good market potential of products manufactured in this sector.
