The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr2O3, 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.

Accordingly, the deteriorated iron grade in the mines unlocks a door to consume the low-grade iron ore fines by beneficiation followed by pelletization . Alternatively, fine mineral crystallization and complex mineral structures in the low-grade oolitic iron ore make it unsuitable for traditional beneficiation strategies.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade …

As is well known, the process of direct reduction and magnetic separation is effective route to deal with low-grade saprolite laterite, but generally limited by the reduction of nickel (iron)-bearing minerals and growth of Fe-Ni alloy particles in the reduction process, causing the low recovery of nickel and iron. To improve beneficiation of ...
