Demand of chromium is increasing day by day because of its various applications in ferroalloys, catalyst, refractories, etc. Chromite is an oxide mineral and major source of chromium. Due to increasing demand, high grade chromite ore is depleting gradually [1]. This necessitates the use of low grade chromite ore after beneficiation.Gravity separation techniques are very effective for chromite ore beneficiation as reported by many researchers [16][17][18] [19] [20][21].

In general, chromite ores are enhanced by the gravity separation method (Demi et al., 2006; Meloy et al., 1994; Tripathy and Murthy, 2012). Flotation is used for some chromite deposits (Tripathy et al., 2013; Wesseldijk et al., 1999), but it has proved economically unfeasible. Beneficiation of low grade chromite ore and its Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a Chromite ScienceDirect

The tailing sample was beneficiated by hydrocyclone, tabling, wet high-intensity magnetic separation (WHIMS), and flotation in order to recover the chromite. A chromite concentrate with 45.29wt% Cr2O3 and a Cr:Fe mass ratio of 1.85 can be produced from these low-grade chromite ore beneficiation plant rejects.India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the Process optimization of a chrome ore gravity concentration
