18/06/2014 · The ore found here is high grade with Cr 2 O 3 (chromium oxide) content varying from 44% to 59% (GSI: 2011). The chromite bearing areas in the two districts have flat topped low hills and rolling grasslands intersected by rivers.

Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultramafic magmas and is one of the first minerals to crystallize. It is because of this fact that Chromite is found in some concentrated ore bodies.

Chromium (Cr) is a grey, hard metal most commonly found in the trivalent state in nature. Hexavalent (chromium(VI)) compounds are also found in small quantities. Chromite (FeOCr2O3) is the only ore containing a significant amount of chromium. The ore has not been found in the pure form; its highest grade contains about 55% chromic oxide (1).
