| 摘 要： | 本论文将两种新型螯合剂与三种钛铁矿常规螯合剂对比，发现新药剂在选择捕收性上更有优势。将新螯合剂与油酸皂复配成新型捕收剂TZ-1，对攀西地区某厂微细粒级钛铁矿进行强化浮选实验研究，以解决该厂微细粒级钛铁矿资源回收率低的问题。实验结果表明，对-0.023 mm粒级的含量高达88%，TiO2品位为15.85%的微细粒钛铁矿原矿，采用新型TZ-1捕收剂配合硫酸和水玻璃使用，经“脱硫—一粗一扫四精”的闭路流程实验，最终获得TiO2品位47.29%，回收率58.41%的钛精矿。结果表明该新型TZ-1捕收剂可以有效解决该厂微细粒级钛铁矿回收率低的问题，同时对微细粒钛铁矿的高效回收利用具有指导意义。

| Abstract: | In this paper, two new chelating agents were compared with three ilmenite conventional chelating agents, and it was found that the new chelating agents had more advantages in selective collection. In order to solve the problem of low recovery of fine ilmenite in a plant Panzhihua–Xichang area, a new collector TZ-1 was prepared by combining the new chelating agent and oleic acid soap. The test results show that for the fine ilmenite raw ore with the content of -0.023 mm particles as high as 88% and TiO2 grade of 15.85%, the new TZ-1 collector is used with sulfuric acid and sodium silicate. After the closed-circuit test of desulphurization, one rough, one sweep and four fine, TiO2 grade of 47.29% is finally obtained. Titanium concentrate with 58.41% recovery. The results show that the new collector TZ-1 can effectively solve the problem of low recovery of fine ilmenite in the plant, and has guiding significance for the efficient recovery and utilization of ultrafine ilmenite. |
