复杂难选铁矿石的合理开发与高效利用已经成为当今钢铁行业的焦点问题，浮选是铁矿石处理最有效的选矿方法之一，具有分选效率高、精矿品位高、回收率提升幅度大等特点，尤其是处理微细粒矿石的选别效果更明显。浮选药剂的合理选择和利用是提高浮选效果的重要方法之一。近年来，随着难选铁矿石占比持续增大，新型浮选药剂研究发展迅速。本工作综述了近年来铁矿石浮选调整剂的研究进展，重点介绍了絮凝剂、分散剂、活化剂、抑制剂的研究现状，讨论了调整剂在铁矿石浮选中的重要作用，总结了铁矿石浮选调整剂尚存的不足之处，并对铁矿石浮选药剂的研究方向进行了展望；针对复杂难选铁矿分选，尤其是含铁硅酸盐型铁矿浮选中所用常规浮选调整剂存在的选择性差、分选效率低等问题，探索研制选择性好、分选效率高、来源广、无毒、廉价的新型调整剂及其组合复配药剂将是未来铁矿石浮选调整剂的研究重点。

With the continual mining of iron ore, the simple and easy separation iron ore reserve continues decreasing, while the occupy of complex refractory iron ore increases year by year. Rational exploitation and efficient utilization of complex refractory iron ore is the focus problem of the steel industry nowadays. Flotation is one of the most effective beneficiation methods for iron ores. It possesses high separation efficiency, high hoist scope of concentrate grade and recovery rate etc., especially for fine grain ores. The effective selection and utilization of flotation reagents is one of the important methods to improve the separation performance. The flotation reagent of iron ore has developed rapidly in recent years with increasing the ratio of refractory iron ore. This work summarized the research progress of iron ore flotation regulators in recent years, highlighted the research progress of flocculants, dispersants, activators, and inhibitors in iron ore flotation, and discussed their important role. Aiming at the complex refractory iron ore separation, especially the iron containing silicates type iron ore flotation, suffers from serious problems of routine regulators, such as poor selectivity and low separation efficiency etc. To explore and research excellent selectivity, high separation efficiency, wide source, non-toxic, and economically feasible novel modifiers and their compounds will be the research emphasis of iron ore flotation regulators.
