Magnetic separation is a technology or process that exploits the difference in magnetic properties between the ore minerals and is employed to separate valuable mineral from nonmagnetic gangues. All materials are affected in some way when The investigations carried out by Bhima Rao et al. (1997), reveals that Cr/Fe ratio of off-grade chromite samples of Orissa, India, can be improved to 1.85–3.0 with a Chrome ore beneficiation challenges & opportunities A

How to determine the chrome ore concentrating method and select the right chrome mining equipment is closely related to the physical and chemical properties of chromium ore. Because chromite is weakly magnetic, the technology of purifying chromium ore with high-intensity magnetic separation has been very mature with the development Chromite ore is geologically associated with gangue materials which have lower density compared to pure chromite (FeO.Cr2O3).
