The geologic sources of chromium are essentially mixtures of spinels of the ideal form RO·R 2 O 3 (, chromite is FeO·Cr 2 O 3), although a more accurate representation of an ore source would be (Mg,Fe)Cr 2 O 4 with silica and alumina gangue materials. The refining processes for chromium metal have been thermodynamically defined by their spinel origins.
