Occurrence and Characteristics of Chromite Deposits ...

The chromite deposits of the eastern Bushveld Complex occur in the Critical Zone, a layered pile consisting mainly of pyroxenite, norite, and anorthosite, with minor gabbro, dunite, and harzburgite. With probable reserves in excess of one billion tons, the deposits are among the major mineral resources of the world.

Chromite - an overview ScienceDirect Topics

Chromite. Chromite is an oxide mineral belonging to the spinel group, a complex mineral containing magnesium, iron, aluminum, and Cr in varying proportions, depending on the deposit, that can be represented as FeCr2O4 or (Fe2+,Mg)[Cr,Al,Fe3+]2O4 (Murthy et al., 2011; Sanchez-Segado et al., 2015). From: Environmental Materials and Waste, 2016

Chromite: Mineral information, data and localities.

"Chromite" is commonly used for any Cr-rich mineral of the spinel group, particularly for the chromite-magnesiochromite series, and much of the mineral referred to as "chromite" in geological and petrological papers and mining statistics is magnesiochromite. The Fe-dominant species - chromite itself - can be FOUND, although uncommonly, in many "chromite" deposits

Chromite-Rich and Chromite-Poor Ophiolites: The Oman Case ...

The chromite deposits are restricted to the Harzburgite Ophiolite Type (HOT) in which chromium has passed into the melt. Although Oman belongs to the HOT group, it seems to have been a particularly fast spreading HOT. It is suggested that in such a situation the transition zone, which is the level where the chromite normally precipitates from the melt, due to temperature drop, could have ...
