Beneficiation: Beneficiation is the process which improves the economic value of the ore by removing gangue minerals. The Committee noted that there has been a continuous depletion of highgrade iron ore in India. Hence, it is necessary to beneficiate lowgrade iron ore into commercialgrade to fulfil the demand for raw material for steel making.
