titanium dioxide processing
Manufacturing process of Titanium Dioxide | Valco Group
Manufacture takes place by either the sulfate process or the chloride process and the main raw materials include ilmenite (FeO/TiO2), naturally occurring rutile, or titanium slag. In essence the process converts the impure TiO2 feedstock into an easy to purify intermediate, separates out the impurities then converts back to pure TiO2 (see ...
