Chromite - an overview | ScienceDirect Topics

Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 ·3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable source of Cr (Sueker, 2006; Glastonbury et ...

Industrial Minerals

Market Brief. Chromite is the commercial name for iron chromium oxide (FeCr 2 O 4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide.In its purest form, chromite comprises chromium (Cr 2 O 3) at 68% and iron oxide (FeO) at 32%.. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite.
