Chromite (FeCr₂O₄) is the principal chromium ore mineral and the only economically significant Cr resource. It forms in podiform and stratiform layered ultramafic intrusions — most notably the Bushveld Complex (South Africa) and the Stillwater (Montana) Complex. Chromite is also the host matrix for druzy uvarovite garnet at Saranovskii (Russia).
Key Facts
- Mohs hardness 5.5.
- Isometric; spinel-group structure.
- Black to brownish-black with submetallic luster.
- Major chromium ore — virtually all Cr metallurgy depends on chromite.
- Common host for druzy uvarovite garnet.
Notable Localities
Bushveld Complex (South Africa) and Stillwater (Montana) host stratiform deposits. Saranovskii (Russia) supplies chromite with druzy uvarovite.
