攀钢高炉渣提取TiO_2及Sc_2O_3扩大试验

SCALE-UP EXPERIMENT ON TiO_2 AND Sc_2O_3 RECOVERY FROM B.F.SLAG ATPANGANG

阐述了用攀钢高炉渣制取颜料级钛白粉和高纯Ｓｃ＿２Ｏ＿３的方法。合理利用酸解液中各组分元素的影响、控制脱铝量、调整钛液总离子浓度、制备活性高的晶种，制出了ＢＡ０１－０１钛白。采用全萃取法从水解后的废酸中提出了品位达９９．９９％的ＳＣ＿２Ｏ＿３，具有推广应用价值。

Methods for preparation of titanium dioxide pigment and high purity Sc_2O_3 from B.F. slag at Panzhihua I.&S. Co. are introduced.The BA01-01 titanium dioxide was produced by rational use of element interaction in acidolysis liquor,control of aluminium removal,modification of total ion concentration in titanium liquor and preparation of high activity seed crystal.Sc_2O_3 of up to 99, 99% grade was recovered from waste acid after hydrolysis using full extraction method. The technology is widely applicable.
