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 high-grade iron ore in India. Hence, it is necessary to beneficiate low-grade iron ore into commercial-grade to fulfil the demand for raw material for steel making.
The beneficiation studies of Suresh (1981) illustrate that low-grade chromite ore of 16%–25% Cr 2 O 3 of Sitampundi area of India, cannot be upgraded by using conventional physical beneficiation techniques like gravity and flotation, due to the intimate association of iron in the lattice of chromite particle. However, they have demonstrated ...
