• Chromite - Wikipedia

    en.wikipedia.org/wiki/Chromite 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.
  • Chromite: The only mineral ore of chromium metal

    geology.com/minerals/chromite.shtml 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.

  • CHROMITE (Iron Chromium Oxide) - Amethyst Galleries

    www.galleries.com/chromite Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies.
