摘　　要：原生钛铁矿石占有率高、品位低、嵌布复杂是我国钛铁矿资源的基本特征,采用传统的磁选工艺,钛铁矿回收率较低。相对于磁选工艺,浮选工艺在细粒物料回收方面具有显著的优越性,是微细粒钛铁矿回收的有效工艺。为了促进钛铁矿浮选工艺技术的进步,系统总结了钛铁矿浮选药剂的研究进展,综述了钛铁矿浮选药剂及其作用机理方面的研究成果。对研究与生产实践中常用的脂肪酸类、膦酸类、胂酸类、羟肟酸类等钛铁矿浮选捕收剂进行了逐一介绍;新型组合捕收剂结合了多种常规捕收剂的优点,是捕收剂开发与应用的重要研究方向;调整剂主要包括钛铁矿的活化剂和脉石矿物的抑制剂,这些药剂在脉石矿物与钛铁矿可浮性相当时,对浮选分离起着决定性的作用。结合现代测试分析方法,分析、综述了浮选药剂在矿物表面的作用方式,为钛铁矿的浮选提供了理论基础,为选矿工作者提供了技术参考。High occupancy,low grade,and complicated inlaying of the primary ilmenite ore are the characteristics of il- menite resources in China. Compared with the low recovery of ilmenite ore using magnetic separation, flotation is an advanced method to recover fine ilmenite particle due to its high efficiency in the field of beneficiating fine minerals. This paper systematiclly summarized the research progress of flotation reagents and reviewed the interaction mechanisms between flotation reagents and minerals in recent years in order to promote the advance of ilmenite flotation. The commonly used ilmenite collectors, such as fatty acids, phosphonic acids, arsenic acid, and hydroxamic acid, are introduced in detail. The novel mixed collectors are the important research object for the development and application of flotation collector, which combine the advantages of conven- tional collectors. Regulators mainly include the activators of ilmenite and the depressants of gangues, which play critical roles when the floatability of ilmenite is similar as that of gangues. The adsorption mechanisms of reagents on the mineral surfaces are explored and analyzed through the modem analytical techniques, which provide a basic theory for the ilmenite flotation and technical references for researchers.
