摘　　要：目前我国应用的赤铁矿浮选捕收剂多数因含有较长烃链而水溶性差,在浮选作业时常需要对矿浆进行加热处理,增加了选厂生产能耗和成本。基于“双碳”背景研发赤铁矿常温捕收剂、低温捕收剂是优化赤铁矿浮选药剂制度、增效降耗的关键途径之一。归纳总结了近年来赤铁矿浮选体系的常温/低温新型捕收剂和复配型捕收剂的研究进展,阐述了有利于实现赤铁矿常温/低温浮选过程的药剂特征活性有机基团及其对生产指标的影响,旨在总结并拓宽赤铁矿新型常温/低温浮选捕收剂设计思路,推动赤铁矿常温/低温浮选药剂的研发与应用,进而逐步实现赤铁矿浮选过程的增效降耗。The majority of hematite flotation collectors currently utilized in China exhibit poor water solubility due to their long hydrocarbon chains.Consequently,the slurry frequently necessitates heating during flotation operations,which increases energy consumption and costs in processing plants.Developing hematite collectors that are effective at normal and low temperatures is one of the pivotal approaches to optimizing the hematite flotation reagent system enhancing efficiency,and reducing consumption,especially within the framework of the"dual carbon"goals.By meticulously analyzing the recent research findings on new normal and low-temperature collectors and compound collectors in the hematite flotation system,the characteristics of reagents conducive to normal and low-temperature flotation processes were elucidated,focusing on the active organic groups and their impact on production indicators.The objective is to summarize and expand upon the design ideas for new types of normal and low-temperature hematite flotation collectors,promoting the research,development,and application of these reagents in hematite flotation processes and gradually achieving enhanced efficiency and reduced consumption.
