AbstractCaTiO3 was decomposed by alkaline roasting method for the production of TiO2. The process included alkaline roasting, water leaching and acid leaching steps. In the alkaline roasting step, the factors Such as roasting temperature and NaOH/CaTiO3 molar ratio were investigated and 99.5% TiO2 Could be extracted from CaTiO3. In addition, it is believed that only ion-exchange between Ca2+ and Na+ takes place, while the structure of TiO32- in CaTiO3 was not destroyed during the roasting process. In the acid leaching step, Ca(OH)(2) Could be completely leached at pH = 6-7 and Na2TiO3 was completely hydrolyzed simultaneously. The crystal structure of the leached sample seemed to be affected by pH and sequent calcination temperature. Finally, a flowsheet was proposed for the extraction of TiO2 from perovskite.
