Rutile: A specific crystal structure of titanium dioxide (TiO 2) that contains roughly 90% TiO 2, about 10% iron (Fe), and quantities of both niobium (Nb) and tantalum (Ta) that are reported to occasionally be more than trace presences. Tantalum: Another rare transition metal that is known for being yellow/gold or a burgundy red in gemstones.
The result is a Ti-rich slag with 83% TiO2 content and Fe-Ti-C composite, a highly valued by-product. Theoretically, refining pure titanium dioxide can be achieved by the same traditional chlorination methods, though, due to the low titanium dioxide content, the process requires higher temperatures than with standard content titanium ores.

mineral. The results show that TiO2 plays a key role in producing cast iron in tatara operations, and the fact that Akome iron sand is known to produce cast iron as it contains higher levels of TiO2. In contrast, Masa iron sand which is known to produce steel (tamahagane) contains much less TiO2 and hence is not suitable to produce cast iron.
