The production of chromite ores from the Sukinda valley comprises of predominantly powdery and friable ore types, and during mining, considerable quantities of low-grade ores (Cr2O3: <40wt%) are also handled. The low-grade ores are beneficiated in chrome ore beneficiation plants in order to obtain high-grade concentrates (Cr2O3: >45wt%).
Conventional beneficiation processes such as flotation, electrostatic and magnetic separation, gravity methods and flocculation–dispersion using chemical reagents to treat the finer iron ore resources often prove to be inefficient, energy-intensive, costly, and environmentally-toxic.
