| 摘 要： | 反浮选工艺以浮选效率高和产品质量好而广泛用于铁矿浮选过程中。在反浮选工艺中，选取高效、经济和环保的抑制剂对反浮选的结果起决定性作用。本文综述了铁矿石浮选过程中有机抑制剂的研究进展，重点介绍了淀粉和纤维素等抑制剂的研究现状，简述了有机抑制剂种类等因素对其抑制性能的影响。虽然有机抑制剂选择性好、分选效率高、价格低廉和绿色环保，但在铁矿石浮选中还存在一些不足之处，因此寻找高效抑制剂替代物和对有机抑制剂改性将会是未来有机抑制剂的研究重点。

| Abstract: | Reverse flotation process is widely used in iron ore flotation process for its high flotation efficiency and good product quality. In the reverse flotation process, the selection of efficient, economic and environmental protection inhibitors plays a decisive role for the reverse flotation results. In this paper, the research progress of organic inhibitors in iron ore flotation process is reviewed, with emphasis on the research status of starch, cellulose and other inhibitors. The influence of the composition of organic inhibitors and other factors on the inhibition difference is described. Although organic inhibitors have good selectivity, high separation efficiency, low price and environmental protection. There are still some shortcomings in iron ore flotation. Therefore it is pointed out that the research focus of organic inhibitors in the future will be to find efficient substitute for organic inhibitors and modify organic inhibitors. |
