Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 ·3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable source of Cr (Sueker, 2006; Glastonbury et ...
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.

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.

Aug 29, 2016· Il n'y a pas de règle permettant de définir le degré d'oxydation d'un atome. Le chrome peut effectivement avoir le degré d'oxydation 2, 3 et 6. Mais dans le principal minerai de chrome, la chromite, qui est un oxyde de fer et de chrome, il est présent au degré d'oxydation +3. C'est donc l'état le plus stable du chrome.

Chromite is the main source of the metal chromium, a metal used to induce hardness, toughness and chemical resistance in steel. It was named after its chemical composition, chromium oxide. The mineral is brownish to black in colour with a dark brown streak. It has a conchoidal or an uneven fracture as well as no distinct cleavage.
