Sulphate process. The ilmenite is reacted with sulphuric acid giving titanium sulphate and ferric oxide. After separation of ferric oxide, addition of alkali allows precipitation of hydrous titanium dioxide. The washed precipitate is calcined in a rotary kiln to render titanium dioxide. The nucleation and calcination conditions determine the crystalline structure of titanium dioxide (e.g. rutile or anatase).

China's dominance in the titanium dioxide industry can be attributed to its vast mineral resources, particularly ilmenite and rutile, which are the primary sources of titanium dioxide. The country possesses an estimated 45% of the world's total titanium reserves, enabling it to maintain a consistent and large-scale production capacity. This has not only secured China's position as a leading producer but also influenced global market dynamics.
