钛铁矿浮选药剂研究现状及展望

Research Status and Prospect of Ilmenite Flotation Reagents

  • 摘要: 浮选工艺中药剂的合理使用可有效选别日渐贫、细、杂的钛铁矿。文章综述了阳离子型、阴离子型和组合型三类捕收剂,有机型和无机型两类抑制剂,金属离子和高锰酸钾等活化剂。文章指出相比传统捕收剂,组合捕收剂由于药剂之间的协同效应,在一定程度上提高了钛铁矿分选指标,但仍未妥善解决问题,需继续加强新型药剂研发和突破,其中阴、阳离子捕收剂配合使用具有不错发展前景;抑制剂通过减少脉石矿物表面活性位点,阻止了捕收剂对脉石矿物的吸附,有机抑制剂和组合抑制剂表现出优良的选别特性,是未来重点研究方向;活化剂通过提高矿石表面活性位点数量及活性,增强了捕收剂对目的矿物的吸附性,但存在污染问题,应加大绿色环保型活化剂的研发力度,以期活化剂早日投入生产,提高工业生产效率。

     

    Abstract: The use of reasonable reagents in flotation process can effectively separate the increasingly poor, fine and miscellaneous ilmenite ore. Cationic, anionic and combined collectors, organic and inorganic inhibitors, metal ions and potassium permanganate activators are reviewed. Compared with the traditional collectors, the combined collectors improve the separation index of ilmenite to a certain extent due to the synergistic effect between the reagents, but the problem has not been properly solved. It is necessary to continue to strengthen the research and development and breakthrough of new reagents. The combination of anionic and cationic collectors has good development prospects. Inhibitors prevent the adsorption of collectors on gangue minerals by reducing the surface active sites of gangue minerals.Organic inhibitors and combination inhibitors show excellent sorting characteristics, and are the key research directions in the future. By increasing the number and activity of active sites on the mineral surface, the activator enhances the adsorption of the collector on the target minerals, but there is a pollution problem. The research on green and environmental friendly activator should be strengthened in order to put the activator into production as soon as possible and improve the industrial production efficiency.
