Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the 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 chromite mine is a place where chromite, an iron, chromium, and oxygen oxide mineral, is extracted. These elements combine, resulting in a dark, glossy mineral which is the main source of chromium. Chromium, in turn, plays a key role in various industries – from making stainless steel rust-resistant to giving that shiny finish to our

Description. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
