  • Chromite - Wikipedia

    Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite. A substitution of the element aluminium can also occur, leading to hercynite. Chromite today is mined particularly to make stainless steel .
