摘　　要：萤石矿床分为单一型萤石矿床和共伴生萤石矿床两大类,一直以来,我国萤石资源的开发利用多以单一型萤石资源为主,现已面临紧缺。共伴生型萤石资源中萤石含量较低,矿石性质复杂,主要脉石矿物除石英外,还含有方解石、天青石、重晶石等碱土金属盐类矿物。这几种矿物表面阳离子质点均为钙离子、锶离子和钡离子,晶体性质和物理化学性质相似,浮选过程中相互干扰,造成萤石与这几种矿物间的浮选分离十分困难。本文总结了近年来共伴生型萤石矿浮选抑制剂、浮选捕收剂和浮选理论方向的研究进展,对存在的技术难点及发展趋势进行了介绍,以期为该类资源的综合利用提供参考。Fluorite deposits can be divided into single type deposits and associated fluorite deposits.For a long time,the development and utilization of fluorite resources in China is mainly a single type of fluorite resources,which is now in short supply.The fluorite content in the associated fluorite resources is low and the properties are complex.In addition to quartz,the main gangue minerals also contain alkaline earth metal salt minerals such as calcite,celestite and barite.Their surface cation sites are calcium ion,strontium ion,barium ion,and their crystal properties,physical and chemical properties are similar.Therefore,it is difficult to separate fluorite from these minerals due to mutual interference in the flotation process.In this paper,the research progress of flotation inhibitors,collectors and flotation theory of concomitant fluorite minerals in recent years is summarized.At the same time,the existing technical difficulties and development trend are introduced,hoping to provide reference for the comprehensive utilization of this kind of resources.
