The first commercial production of TiO2 began in the early 20th century, using the sulfate process. This method involved reacting ilmenite ore with sulfuric acid to produce titanium sulfate, which was then calcined to obtain titanium dioxide. However, this process had several drawbacks, including high energy consumption, generation of large amounts of waste, and release of harmful gases such as sulfur dioxide. As a result, many factories transitioned to the chloride process, which offers higher purity TiO2 and reduced environmental impact.
