of their low capacities and in terms of the requirement for the iron ore to be susceptible to magnetic fields [5]. Flotation, on the other hand, is used to reduce the content of impurities in low-grade iron ores [1-2,5]. Iron ores can be concentrated either by direct anionic flotation of iron oxides or

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.

Beneficiation of low grade iron ore was carried out by selective flocculation process using different flocculants namely starch amylopectin (AP) and grafted copolymer of amylopectin (GAP).
