EC number: 308-551-1 | CAS number: 98072-94-7 Natural ilmenite ore is concentrated by selective removal of impurities, chiefly iron, to yield a product enriched in titanium dioxide. The process consists of an optional oxidative roast followed by a reductive roasting stage, an acidic leaching stage and washing and drying the product. Alternatively the process consists of selectively chlorinating the iron oxide present in the reduced ore.
