Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr 2 O 4.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 (MgCr 2 O 4).A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).
