2020-2-19 · Low-grade deposits and the fines resulting in the mining operations cannot be economically used. Therefore, beneficiation of low grade and finely disseminated chromite ores is becoming important, due to the shortage of high grade ore reserves [1,2]. High grade chromite ore commonly was mined from Ingassana hills deposits in the Blue Nile region.
