Chromite Wikipedia

Chromite is a crystalline mineral composed primarily of iron oxide and chromium oxide compounds It can be represented by the 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 through the production
