NMDC has signed a pact with the Colorado School of Mines, adding an international research partnership to the toolkit of India's largest iron ore miner. Collaborations of this kind typically target better exploration methods, mining efficiency and beneficiation know-how — capabilities that matter increasingly as India pushes to lift domestic ore output and quality in step with fast-growing steel capacity. Stronger technical depth at NMDC ultimately serves every consumer of Indian ore, from pellet and sponge iron makers to the blast furnaces of the major mills.
