The sulphate process was the first commercialized technology to obtain the titanium dioxide pigment. In this process, ilmenite (40% - 60% TiO 2) or titanium slag (72% - 85% TiO 2) or even a carefully controlled blend, is digested with concentrated …
(Kamala, 2006). The titanium slag produced from this process represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process. In the case of the chloride process, the titanium-rich slag is further acid-leached by a hydrometallurgical process. As a leachant, hydrochloric acid is preferred to other acids
