NMDC Ltd. has taken over a silica sand mining and beneficiation project from Uttar Pradesh State Mineral Development Corporation Ltd. The plant is designed to produce beneficiated high purity silica sand to a capacity of 300,000 tonnes per year as the raw material for production of float/sheet glass.

NMDC Steel Limited
NMDC set up a 3 MTPA capacity greenfield Nagarnar Steel Plant based on HiSmelt technology, 16 km from Jagdalpur in Chhattisgarh state, with an estimated outlay of Rs 20000 crore.

A pure-play miner, NMDC had in 2009–10 conceived the Nagarnar steel plant with the intention of moving up the value chain and diversifying its portfolio. The idea was also to hedge itself against the vagaries of iron ore prices.

The plant site is around 16 km from Jagdalpur and 6 km from the Orissa–Chattishgarh border. The nearest railway station is Amaguda (around 2 km). The site is located on National Highway NH 30. The nearby airports are Jagdalpur, Raipur & Vishakhapatnam and the nearest seaport is Visakhapatnam located at a distance of approx 325 km. The nearest river is Indravati, located at a distance of 3 km.

In 2023 NMDC Steel became a publicly traded company on the Bombay Stock Exchange and National Stock Exchange of India, after a demerger from NMDC in 2022.
