摘要: 为了考察含钛炉渣作为硫酸法钛白生产原料的可行性,分析研究了含钛炉渣的物相组成以及硫酸法钛白生产过程中杂质成分氧化钙、氧化镁、三氧化二铝、二氧化硅、全铁(TFe)、钒和铬等的去向,并对制得的钛白初品质量进行了分析。结果表明,含钛炉渣中的杂质元素二氧化硅、钒、铬和氧化钙主要进入酸解残渣,氧化镁、三氧化二铝、全铁等主要进入偏钛酸过滤洗涤得到的废液中,进入最终钛白产品的杂质含量很低,不会影响产品质量。

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
