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.

Description of key information
Synthetic Rutile has a relative density between 3.81 to 3.92.
Key value for chemical safety assessment
Additional information
The specific gravity (relative density), was determined for two different batches of Ilmenite (2009 -717 -SRS (ILU02) and 2009 -727 -SRP (ILU01)) was determined by pycnometer method.
Two measurements were conducted, respectively and following results for the relative density were obtained
2009 -717 -SRS (ILU02) = 3.92
2009 -727 -SRS (ILU01) = 3.81
