Chromite Wikipedia

Chromite is an iron chromium oxide: FeCr 2 O 4. It is an oxide mineral belonging to the spinel group . Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4 ); [5] substitution of aluminium occurs leading to hercynite (FeAl 2 O 4 ).
