| 摘 要： | 对TiO2品位为13.43%的内蒙古磨石山沉积变质型锐钛矿开展了试验研究。以YS-3为捕收剂的正浮选获得了TiO2品位37.95%、回收率23.79%的钛精矿; 以NaOH为pH调整剂、淀粉为抑制剂、石灰为活化剂、164为捕收剂的反浮选获得了TiO2品位30.07%、回收率70.46%的钛精矿。结果表明: 反浮选效果优于正浮选, 能更好实现钛矿物富集。

| Abstract: | Experimental study was carried out on the flotation of a sedimentary-metamorphic anatase ore graded 11.43% TiO2 from Moshishan Mine in Inner Mongolia. When adopting a direct flotation process, a titanium concentrate with TiO2 grade and recovery of 37.95% and 23.79%, respectively, can be obtained with YS-3 as the collector. While, the reverse flotation with NaOH as pH regulator, starch as depressant, CaO as activator and 164 as collector, led to a titanium concentrate with TiO2 grade of 30.07% at 70.46% recovery, which has verified that reverse flotation performs better than direct flotation, as it can enhance the enrichment of titanium minerals. |
