Magnetic separation techniques may be useful after reduction for the beneficiation of low grade chromite ore. The sample collected from the sukinda mines is characterized by XRD which shows predominant phases like maghemite, chromite, silica, magnesia and alumina. The raw ore is crushed and ground to below 75 micrometer size.

1. The compositions of the South African chrome ore are relatively simple, chromite is the main mineral, and accounts for more than 91%; chlorite and forsterite are the main gangue minerals. The main elements in the pyrite are Mg, Al, Si, O and a small amount of Fe; the main elements in the forsterite are Mg, Si and O; 2.
