The chromite ore at Topraktepe was mined between 1986 and 1991 with the Cr2O3 grade of approximately 55 %. 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.

This study was performed on disseminated low-grade chromite ore, Gedarif State, Umm Saqata-Qala Elnahal, to treatment the ore by Heavy media separation (HMS) with low intensity magnetic separation (LIMS) for course fraction size (-212+75) μm and
The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr 2 O 3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.
Initially, the low grade chromite ore (containing 34.8% Cr 2 O 3) was reduced at 1200 0 C for 80 minutes with 30% coke fines by weight, before being subjected to magnetic separation. The reduction by coke leads to conversion of higher state of iron oxides converted to lower state of iron oxides. The pre-reduced samples are then characterized by ...
