  • 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.

    IntroductionTransport of Chromium Into The EnvironmentBioavailabilityImpacts on Human HealthPrevention Or MitigationRelated LinksPhoto CreditsChromium is used mainly in metal alloys such as metal-ceramics, stainless steel, and is used as chrome plating. It has high value in the industrial world because it can be polished to a mirror-like finish, and provides a durable, highly rust resistant coating, for heavy applications. On the flip side, chromium can also provide health benefits to humans.See more on serc.carleton.edu
