Beneficiation of low grade chromite for preparation of

ABSTRACT Low grade chromite samples from rejected dumps and over-burdens were taken for beneficiation study to produce a material suitable for charge-chrome preparation. The chromite samples with about 25% Cr203 in average, are ferruginous, but non-magnetic and contain 30-40% Fe203, Si02 content is significantly low.
