Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle. It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum. The vast Bushveld Igneous Complex of South Africa is a large layered mafic to ultramafic igneousbody with some layers consisting of 90% chromite making the ra

Chromite: The only mineral ore of chromium metal

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.
