Chromite, the only commercial source of chromium, is a spinel group mineral that occurs in ultramafic igneous rocks and further occurs exclusively in rocks formed by the intrusion and solidification of molten lava or magma, which is very rich in the heavy iron-containing minerals such as pyroxenes and olivine. In addition, it is also found in metamorphic …
