Bauxite was named after the village Les Bauxin southern France, where it was first recognized as containing aluminium and named by the French geologist Pierre Berthier in 1821. Bauxite is an aluminium ore and is the main source of aluminium. This form of rock consists mostly of the minerals gibbsite Al(OH)3, boehmite γ- AIO(OH), and diaspore α-AIO(OH), in a mixture with the two iron oxides goethite and hematite, the clay mineral kaolinite, and small amounts of anatase TiO2.
Indian bauxite resources are confined to peninsular shield excepting the occurrences in Jammu in the extra peninsular region. In the peninsular region about 85% of the total reserve is associated with ‘high level’ laterite occurring along the eastern and western coasts of which nearly 74% of the reserve is restricted to east coast. About 10% of the total reserve occurs amidst inland plateaus. The major bauxite deposits of India are generally associated with laterite capping occurring as blankets on the plateaus of high elevation of 700 m to 2100 m above MSL in parts of Orissa, Andhra Pradesh, Bihar, Madhya Pradesh, Maharashtra, Karnataka and Tamil Nadu.
Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. Approximately 70% to 80% of the worlds dry bauxite production is processed first into alumina, and then into aluminium by electrolysis as of 2010. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory.

ECONOMIC SIGNIFICANCE It is the primary source of aluminum metal. It is extremely important economically due to the very widespread use of aluminum. It is used in everything from soda cans to candy wrappers to cars, aircraft, and boats. It is the most common light weight metal in use.
India is favorably endowed with large reserves (3037 million tones of institute reserve) of Bauxite. In terms of bauxite reserves, India holds the fifth place in the world. Of all non ferrous metals, aluminium production in India is large enough to meet the growing demand within the country and has a surplus for export. During the year 1991-92, Rs.440 crores of foreign exchange was earned by the country through export of bauxite and alumina.

MALCO is engaged in the mining ofbauxite, Manufacture of alumina, aluminium and downstreamproducts like rods and rolled products. The company minesbauxite from own captive mines located in the close proximityof the plant in Southern India
In 2010, Australia was the top producer of bauxite with almost one- third of the worlds production, followed by China, Brazil, India, and Guinea. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries. Increased aluminium recycling, which has the advantage of lowering the cost in electric power in producing aluminium, will considerably extend the worlds bauxite reserves.
