The ore was classified as 'Podiform type Al-chromite' (Zedef et al., 1994). During the mining period, about 200 000 tons of ore were recovered from the central part of the chromite body where the Cr2O3 grade is the highest. When the Cr2O3 grade lowered to <50 %, the mine was abandoned, in October 1991.
The beneficiation of low grade (Cr2O3% 26.88) chromite ore has been investigated using table. Optimization has been carried out using box-behnken statistical design (BBD).
