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.

Chromite, or iron chromium oxide (FeCr2O4), is the mineral source of chromium. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. High-purity chromite deposits are rare, due to the natural replacement of chromium and ferrous iron by other elements.

Apr 6, 2021The chromite is liberated essentially in the minus 100-mesh fraction; however, a small amount of chromite remains locked in the minus 325-mesh fraction. The Alamether sample was a dunite consisting primarily of olivine, with a small amount of disseminated chromite. Very small amounts of orthopyroxene and chlorite also were observed. A study of sized fractions indicated that the chromite is ...

The PGM grains enclosed in chromite formed by a different mechanism to the PGM grains outside chromite. During the crystallization of the chromite the magma was sulfide undersaturated and Ru, Os, Ir, and Rh partitioned into chromite thereby enriching the chromitite layers in IPGE. As the cumulate pile cooled, the fractionated silicate liquid became saturated in a BMS liquid and this migrated ...
