Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891.Generally, it is sourced from ilmenite, rutile and anatase.It has a wide range of applications, including paint, sunscreen and food coloring.

In this process, hydrated titanium dioxide is added to the leaching solution as seeds to increase the rate of precipitation of titanium salts and to improve the removal of iron. This also allows the separation of iron from the ore at lower temperature and at a sulphuric acid concentration that makes the construction of the reactors economical.

acid: iron titanium oxide + sulfuric acid titanium dioxide + iron sulfate + water FeTiO 3 + H 2 SO 4 TiO 2 + FeSO 4 + H 2 O Step 2 Next we change titanium dioxide into titanium(IV) chloride. This involves using carbon but is not the final step in extraction of the metal.

The chloride process is used to separate titanium from its ores. In this process, the feedstock is treated at 1000 °C with carbon and chlorine gas, giving titanium tetrachloride.Typical is the conversion starting from the ore ilmenite:. 2 FeTiO 3 + 7 Cl 2 + 6 C → 2 TiCl 4 + 2 FeCl 3 + 6 CO. The process is a variant of a carbothermic reaction, which exploits the reducing power of carbon.
