CONCENTRATION OF CHROMITE BY MEANS OF

Chromite is primarily used as a refractory material. For this purpose, the Cr 2 O 3 content of chromite should be more than 45%. Hence, concentration of chromite is often required. It is usually performed by gravity methods based on differences between the densities of chromite and gangue minerals, especially serpentine and olivine.
