Where is chromium found on Earth? Chromium is only found rarely as a free element in nature. It is mostly found in ores scattered throughout the Earth's crust where it is about the twentyfourth most abundant element. The main ore that is mined for the production of chromium is cromite.
The world chromium ore production originates from the mineral chromite (a chromiumiron oxide) in the rock chromitite. The majority of the chromium ore resources of the world are to be found in the Bushveld Complex of South Africa and the Great Dyke of Zimbabwe, where it occurs as numerous thin stratiform chromitite layers.
Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.
General Chromium Information. Environment: In heavy sands derived from the contact metamorphic zone between a siliceous marble and ultramafic rock. Locality: Sichuan Province, China. Link to Location Data. Name Origin: From the Greek, chroma = "color", in allusion to .
Chromite is the mineral ore of the metal Chromium, and the chromium must often be extracted from the ore and purified before it is used. Chromium is an important ingredient in steel; it gives this metal increased hardness and toughness, and it helps it reduce chemical erosion over time.
Chromium is an opensource browser project that forms the basis for the Chrome web browser. But let's take a little deeper look at what that means. When Google first introduced Chrome back in 2008, they also released the Chromium source code on which Chrome was based as an opensource project.
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.

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 ultramafic 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.
