"chromite ore" under three major ore grades, namely: • "metallurgical ore" (Cr2O3 > 48% and Cr/Fe > 2); • "chemical ore" (Cr2O3 > 45%); and • "refractory ore" (Cr2O3 > 30%, high Al2O3, and SiO2 < 2.5%). About 85% of the world production of chromite ore (~12 million tonnes (Mt)) is consumed by the metallurgical industry.
