The production of titanium dioxide traditionally involves processes that can be energy-intensive and potentially harmful to the environment. However, leading manufacturers have embraced cleaner technologies such as the chloride process, which yields high-purity TiO2 while significantly reducing waste and emissions. By utilizing this method, factories can minimize the release of contaminants and conserve resources more effectively than older techniques.

The production process within these factories is intricate and requires precise control over chemical reactions. First, the raw rutile ore is extracted from mines and then crushed into a fine powder. This powder undergoes a series of leaching processes to remove impurities. Afterward, it is subjected to the chlorination process, where it reacts with chlorine gas at high temperatures to produce titanium tetrachloride. This compound is then refined further through vapor deposition or oxidation to yield high-purity titanium dioxide.
