ROM (Run of mine)

Chromite is the commercial name for iron chromium oxide (FeCr2O4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite. High purity deposits are rare owing to replacement by certain elements. In nature, ferrous iron tends to be partially replaced by magnesium, while chromium may be partially replaced by aluminium or ferric iron.

Chrome ROM refers to the raw mined material as it is delivered by the mine cars, skips, or conveyors and prior to treatment of any sort.
