Industrial Minerals

Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite. High purity deposits are rare owing to replacement by certain elements. In nature, ferrous iron tends to be partially replaced by magnesium, while chromium may be partially replaced by aluminium or ferric iron.

Chromite - an overview | ScienceDirect Topics

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

Geology - rocks and minerals

Chromite, an oxide mineral, is the major ore of chromium. It is often used for the bricks and linings of blast furnaces as it can withstand very high temperatures. Chromite is one of the first minerals to crystallise in deep ultra- mafic magmas, and becomes concentrated as it sinks to the bottom of the magma chaer .

Department for Energy and Mining - Chromite

Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. It has the chemical formula FeCr 2 O 4, and a theoretical composition of 32.0% FeO and 68.0% Cr 2 O 3. In its natural form it occurs in solid solution with other minerals in the spinel

Chromite | Physical - Optical Properties, Uses,

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. It is sometimes found as a crystalline inclusion in diamond.
