Chromite ore beneficiation: prospects and challenges
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 ...
