Abstract
The chromite deposit at Boula-Nausahi Igneous Complex is of stratiform type where chromite occurs as layers in ultramafic rocks. The chromites in this complex can be ascribed to early and late stage crystallization based on differences in their physical, chemical and beneficiation characteristics. The early stage chromites are characterised by their association with serpentinite, coarser grain size, nonmagnetic nature, high Cr content, high Cr/Cr+Al ratio, average chemical composition (Cr203-51.9%, FeO-26.9%, MgO-lO.3%, A1203- 10.2%, Ti02-0.45%, V203-.2%, Cr/Fe-1.74) and amenability to simple beneficiation techniques. On the contrary, the late stage chromites are characterised by their association with fine grained fibrous and magnetic silicates, fine grain size, magnetic behaviour, low Cr content, low Cr/Cr+Al ratio, average chemical composition (Cr203-27%, FeO-53.7%, MgO-6%, Al203-10.5%, Ti02-2.5, V203-0.4% and Cr/Fe-0.45) and difficult to beneficiation.
