What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Market Brief. Chromite is the commercial name for iron chromium oxide (FeCr 2 O 4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide.In its purest form, chromite comprises chromium (Cr 2 O 3) at 68% and iron oxide (FeO) at 32%.. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite.
