Apr 01, 2011 The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr 2 O 3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.
