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(MgCr₂O₄). A substitution of the element aluminium can also occur, leading to hercynite (FeAl₂O₄). Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy.
