杂质成分在含钛炉渣硫酸法制钛白中的去向分析

Abstract

Abstract: The feasibility of low grade titanium slag as raw material for the production of sulfuric acid process titanium dioxide was studied.The phase composition and the distribution of impurities，such as CaO，MgO，Al₂O₃，SiO₂，TFe，V，and Cr，from the low grade titanium slag during the manufacturing process of titanium dioxide by sulfuric acid process were analyzed.The quality of initial product of titanium dioxide was further studied.Results showed that the impurities，such as SiO₂，V，Cr，and CaO，were mainly distributed in the acid composition residue，while the others，such as MgO，Al₂O₃，and TFe，were mainly distributed in the waste water coming from the filtrating and washing process of hydrolysate. The minor amounts of impurities remaining from the raw materials were not enough to affect the quality of the final product of titanium dioxide.

Key words: low grade titanium slag, phase structure, sulfuric acid process, titanium dioxide, impurity composition
