iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Similar to hydrocyclones enhanced by flotation, hydrocyclones enhanced by control particles (i.e., solid particles, droplets, and gas-liquid composite drops) can really enhance the hydrocyclone separation, especially the separation of ions, molecules, and their aggregates.

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.
Applications include heavy minerals, ilmenite, manganese and iron ore (haematite) beneficiation; PGM upgrading as well as manganese recovery from slimes dams. This offers new approaches and technology for solving para-magnetic minerals separation processes that are as efficient as they are cost-effective.
