Chromite ore processing residue is an industrial waste material generated by the manufacturing of chromates for chromite ore. Chromium is present in the trivalent state in the ore as chromium iron oxide (FeCr204). In this state, the chromium is inert and is not soluble in either acid or water. To produce the hexavalent, water-soluble
