It is owned by the Government of India and is under administrative control of the Ministry of Steel.It is involved in the exploration of iron ore, copper, rock phosphate, limestone, dolomite, gypsum, bentonite, magnesite, diamond, tin, tungsten, graphite etc. It is India's largest iron ore producer and exporter producing about 30 million tons of iron ore from 3 fully mechanised mines in Chhattisgarh and Karnataka. It also operates the only mechanised diamond mine in the country at Panna in Madhya Pradesh. The demand for steel will continue to grow in the years to come and this in turn would call for increased demand for iron ore. NMDC is gearing itself to meet the expected increase in demand by enhancing production capabilities of existing mines and opening up new mines - Deposit -11B in Bailadila sector and Kumaraswamy in Donimalai sector. The production capability would increase to around 50 million tonnes per year in coming years.
