Bauxite Resources of Odisha
Bauxite deposits of Odisha are of diverse parentage. More than 95% of the bauxite resources of the state come under East Coast Bauxite (Eastern Ghats Mobile Belt) located in the Southern and Western part of the state i.e. Koraput, Rayagada, Kalahandi, Bolangir districts. The other deposits, smaller in dimensions are residual products of lateritisation of metavolcanics as in Dholkatapahar (Kuanr) of Keonjhar district and Similipal Complex belonging to Similipal Group, shales of Banded Iron Formations of Nuamundi Group as in Tantra, Kusumdihi of Sundergarh district and shales of Khariar high land Group of Nuapada district equivalent to Vindhyan Group.
The bauxite deposits explored by the Directorate, GSI, MECL etc. together add up substantially to the total resources of the State which amounts to 1846 million tonnes of all category. From 2003-04 up to 31.3.2009 the 28.8 million tonnes of bauxite ore has been produced from different bauxite mines of Odisha mostly from Panchpatmali mines of NALCO. So the presently available resource of bauxite in Odisha stands at 1817.2million tonnes.
Production, Bauxite based Industries and Prospects.
Bauxite production in the state is expected to rise significantly in the coming ten years with a number of MNCs are signing MOUs with Govt. of Odisha for exploration and exploitation of Bauxite for setting up Alumina plants. There are total 11 bauxite mining leases in Koraput, Raygada, Sundergarh districts producing annually about 4.8million tonnes bauxite. Panchpatmali is the largest mechanised mines of the state. NALCO a scheduled A Central PSU is the largest integrated alumina and aluminium complex in the country has its Bauxite mines at Panchpatmali, Alumina refinery at the foothills of Panchpatmali hills and alumina smelter and captive power plant at Angul. The present mining capacity of Panchpatmali mines is 4.8 MTPA which is being further augmented to 6.3 MTPA under second phase of expansion. The alumina refinery at Anugul has a capacity of 1.575 MTPA, which is being expanded to 2.1 MTPA. The aluminium smelter at Anugul has the capacity of 0.345 MTPA and is in the process of expansion to enhance its capacity 0.46 MTPA. In the year 2008-09 NALCO has produced 4.7 Mt of Bauxite, 1.58 Mt of Alumina and 0.36 Mt of Aluminium.
