Chromite Ore - an overview ScienceDirect Topics

Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

DETERMINATION OF FEO IN CHROMITE ORE – MSK

The chromite ore is normally having a composition of FeCr2O4 which may be written as FeO.Cr2O3. In some ore Fe is partially replaced by Mg as (Fe, Mg) Cr2O4. The ore may have Fe in other form besides being present in the spinel. An accurate determination of FeO content is extremely important in chromite ores and refractories made with them.
