Conventional beneficiation techniques are not capable of improving the grade of rejects, because of liberation at very finer size. Beneficiation at ultrafine size becomes difficult, once the reject or low grade ore is roasted to magnetite and subjected to grinding, liberation takes place due to thermal degradation as well as size reduction.
