Chromite - Department for Energy and Mining

Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. It has the chemical formula FeCr 2 O 4, and a theoretical composition of 32.0% FeO and 68.0% Cr 2 O 3. In its natural form it occurs in solid solution with other minerals in the spinel group, so chrome contents are less than the theoretical 68%.
