Aluminium is obtained mainly from bauxite. Though several ores contain aluminium, it is from bauxite, a reddish-brown, residual clay-like substance, that alumina and later aluminium is obtained. Bauxite deposits are formed by the decomposition of a wide variety of rocks rich in aluminium silicates. Aluminium is considered to be an important metal because of its properties and wide variety of uses. (i) It combines the strength of metals such as iron with extreme lightness. So it is used for manufacturing of aircrafts and transport vehicles. (ii) It has great malleability. It is used for construction purposes to make door, windows, rods and for making utensils. (iii) It also has quality of good conductivity and is used in electrical conductors.Rich deposits of bauxite, the ore of aluminium, are found mainly in the Amarkantak plateau,Maikal hills and the plateau region of Bilaspur-Katni in Madhya Pradesh and Chhattisgarh. Orissa is the leading producer accounting for about 45 per cent of the total bauxite production in the country. Panchpatnali deposits in Koraput are an important bauxite reserve in Orissa.
