| 摘 要： | 以攀西地区高钛型高炉渣经磁选、硫化焙烧-水浸、盐洗处理后所获的富钛产物为原料,采用稀硫酸浸出法提取其中的钛组分.考察了硫酸质量分数、温度、酸渣质量比和时间对钛浸取率的影响.采用XRF和XRD对富钛产物和酸浸渣的化学成分与物相组成进行了研究.结果表明,富钛产物中Ti02含量超过35％,主要以无定型水合氧化钛和钙钛矿形式存在;提取钛的最佳条件为:硫酸质量分数60％,温度160℃,酸渣质量比(1.25～1.5):1,时间2.5h,Ti02浸取率可达90％以上,且纯度较高;酸解过程中,无定型水合氧化钛最先溶出,其次是钙钛矿,最后是部分透辉石.该工艺具有用酸浓度低、酸解时间短、Ti02浸取率高等特点,对高钛型高炉渣资源化利用具有重要的意义.
