Gravity separation, flotation, high gradient magnetic separation (HGMS) and their combinations are commonly applied to separating fine-grained ilmenite. HGMS is used for industrial-scale pre-separation of low-grade fine-grained ilmenite, which can effectively remove non-magnetic minerals such as kaolin and feldspar.

Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals. However, chromite ore from Sukinda region, India, is a typical ore body with high iron content in the chromite spinel as well as gangue content in the form of oxide and hydroxides of iron-bearing ...

The Cr:Fe ratio (chromium-to-iron mass ratio) of chromite affects the production of chrome-based ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the application of magnetic separation to fine chromite from the Sukinda region of India to enhance its Cr:Fe ratio has been reported.

There are proven and well established widely accepted techniques for concentration of chromite ores such as spiral concentration, jigs and shaking tables. However, these techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75μm) resulting in this size fraction lost to the tailings.
