Chromite: The only mineral ore of chromium metal
A solid solution series exists between the mineral chromite (FeCr 2 O 4) and the isomorphous mineral magnesiochromite (MgCr 2 O 4). Intermediate specimens can be rich in iron ((Fe,Mg)Cr 2 O 4) or magnesium ((Mg,Fe)Cr 2 O 4). For convenience in communication, these minerals are often referred to collectively as "chromite."
