National Mineral Development Corporation (NMDC) was promoted by the Government of India in 1958. It is involved in the exploration of wide range of minerals including iron ore, copper, rock phosphate, lime stone, dolomite, gypsum, bentonite, magnesite, diamond, tin, tungsten, graphite, beach sands etc. NMDC is India`s single largest iron ore producer and exporter, presently producing 20.74 million tons of iron ore from three fully mechanized mines at Bailadila and Donimalai. NMDC is operating the only mechanized diamond mine in the country producing around 80,000 carats at Panna in Madhya Pradesh. The calibrated ore from Bailadila deposits has substituted the iron ore pellets in sponge iron making and hence became an important raw material for major gas-based sponge iron and steel producers like Essar Steel, Ispat Industries, etc. NMDC has a joint venture with Indian Rare Earths Ltd and AP Mining Development Corporation Ltd for the development of Bhimunipatnam beach sands into heavy minerals. It also has a joint venture with the Indian Railways, SAIL and the Madhya Pradesh Government for a railway line between Bailadila iron ore mines and Rowghat, enabling supply to the Bhilai Steel plant. NMDC is planning an expansion by opening up new mines in Bailadila and Donimalai sector with a capacity of around 23 million tonns per year. NMDC is also diversifying into low silica limestone through the takeover of a silica sand mining and beneficiaton project from Uttar Pradesh State Mineral Development Corporation Ltd.
