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 ...

Chromite. Chromite is the commercial name of iron chromium oxide (FeCr2O4), a mineral comprised of chromium and iron oxide that is naturally found in the earth's mantle. When extracted, it is referred to as chrome ore. Chromite is crucial for the production of ferrochrome, an alloying agent in manufacturing stainless steel.
