In the context of titanium dioxide determination, the process generally begins with the sample preparation, where a known mass of the sample containing TiO2 is dissolved or digested appropriately. The subsequent steps involve adding a precipitating agent, such as ammonium sulfate or sulfuric acid, to the prepared solution, which facilitates the formation of a titanium precipitate. This precipitate is often titanium hydroxide, which is not only insoluble but can be easily filtered out from the liquid phase.

Various titanium-rich minerals, including ilmenite and rutile, can serve as starting materials for the production of highly purified Titanium Dioxide. The predominant method employed in Titanium Dioxide production is the chloride process. In this process, the mineral, along with coke and chlorine, undergoes a reaction within a fluidized bed, resulting in the formation of primarily titanium tetrachloride and carbon dioxide. Subsequently, the titanium tetrachloride undergoes purification and conversion to Titanium Dioxide. Another method involves treating ilmenite with sulfuric acid to manufacture the chemical.
