| 摘 要： | 基于硫酸钛白生产工艺的现状，将钛白废硫酸综合利用与富钛料的生产相结合，开展了钛白废酸加压浸出钛精矿制备富钛料的实验研究，并分别考察了酸矿比、浸出温度、浸出时间等因素对富钛料品位的影响。研究结果表明：在酸矿比（mL/g）为8∶1、酸浸温度为150 ℃、酸浸时间为7~8 h的条件下，可获得二氧化钛品位达80%以上的富钛料。通过XRD分析可知，酸浸完成后，钛精矿中的主要物相FeTiO3已转换为富钛料中的二氧化钛物相。

| Abstract: | Based on the present situation of the sulfuric acid titanium dioxide production process，the comprehensive utiliza-
tion of titanium dioxide waste acid and the preparation of Ti-rich material were combined.The experimental study on titanium concentrate leaching to prepare Ti-rich material with titanium dioxide waste acid was carried out.The influences of acid-min-
eral ratio，leaching temperature，and time etc.on the grade of Ti-rich material were investigated.Research results showed that：in a acid-mineral ratio（mL/g） of 8∶1，leaching temperature of 150 ℃，and leaching time of 7~8 h，the Ti-rich material with
TiO2 grade of more than 80% could be obtained.Through XRD analysis，the main phase FeTiO3 of the titanium concentrate has been converted into the TiO2 phase of the Ti-rich material after acid leaching |
