Chromium is largely used as alloying elements in steels for production of stainless steels. It is added in form of ferro-chromium, which is presently imported from Russia and Germany to meet the need of Nigerian Steel Industry. Chromite ore (FeOCr2O3) is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of Zamfara State.

The samples assaying 36.84% of Cr2O3 was subjected to beneficiation process in order to enrich the ore, in terms of the Cr2O3, using magnetic separation. The results obtained after the analysis of the beneficiated ore using wet chemical analysis and Atomic Absorption Spectrometer shows that Cr2O3 content increased to 48% with a maximum CrFe ratio of 6.21.
