Ilmenite Sand Direct Leaching Kinetics in Hydrochloric …
a large amount of ilmenite ore, and producing high-quality TiO 2 pigments. Furthermore, the direct leaching process is still popular because HCl that has been used as a leachant can be regenerated. The direct leaching of ilmenite from iron sand can also result in high Ti recovery, particularly if the ilmenite is partially weathered.
