Investigations were carried out to improve the chromium–to–iron ratio of two off–grade chromite samples from Orissa, India, having different physical natures. The results of these investigations indicated that the chromium–to–iron ratio could be improved from 1.85 to 3.0 with around 10% to 30% recoveries by high–intensity magnetic separation of the washed ores. A common flowsheet is suggested for processing of these two ores.
