Chromitite is an igneous cumulate rock composed mostly of the mineral chromite.It is found in layered intrusions such as the Bushveld Igneous Complex in South Africa, the Stillwater igneous complex in Montana and the Ring of Fire discovery in Ontario.. Chromitite typically forms as orthocumulate layered lenses in peridotite rocks, at times intergrown with other oxides such as magnetite and ...
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.

Description. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.

Chromite crystals in olivine in a primitive basalt. Chromite is dark-brown to opaque at full thin section thickness. Chromite is a spinel-type mineral, like magnetite, and has an extensive solid solution in the magnetite composition direction. Cr-Mg-Al-rich chromites are realtively transparent, and can be dark-brown at full thin section thickness.
Description of Minerals and Rocks. The terms mineral and rock are often confused. They are frequently used together, and the materials they describe are closely related.

The Cr/Fe ratio of the chromite generally varies from 2.6 to 3.6; at least 90% of the chromite is with these limits (Gill, 1922). Workings: The area was discovered about 1910 to 1915, and some minor development and production occurred in 1920 (Brooks, 1922).

Chromite is a heavy, black mineral that has about the same specific gravity as barite. Its hardness is close to that of steel, but it can usually he scratched with a knife blade. The brown streak (powder of the mineral) ordinarily distinguishes chromite from other similar-appearing heavy black minerals, for most of these have black streaks.
Cromita. La cromita es un mineral de composición Fe Cr 2 O 4 perteneciente al grupo IV ( óxidos) según la clasificación de Strunz . Llamado en un principio fer chromate alumine por Louis-Nicolas Vauquelin y Tassaert ( 1798 ), el nombre de cromita se debe a Wilhelm Karl Ritter von Haidinger ( 1845) y hace referencia a su contenido de cromo.
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.
