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.
