摘　　要：萤石作为一种不可再生的战略性非金属矿产资源,广泛应用于国防、化工、冶金、光学等领域。我国萤石资源储量丰富,但贫矿多、组成复杂、选别难、综合利用率低。概述了我国萤石资源的储量、分布、成矿成因及开发利用现状,在分析萤石晶体结构、致色机理等性质的基础上,详细阐述了萤石选矿工艺研究进展,并分析了萤石与方解石浮选分离、低温浮选药剂、矿浆难免离子的影响等萤石选别关键技术难题,最后针对我国萤石资源开发利用中存在的问题提出了对策建议,为我国萤石资源的高效开发利用提供思路和解决方案。As a rare and non-renewable strategic non-metallic mineral resource,fluorite has been widely used in many fields such as national defense,chemical industry,metallurgy,optics.Fluorite resource reserves are abundant in China,but there are many lean ores with complex composition and low recovery.This study summarizes the reserves,distribution,metallogenic genesis and utilization of fluorite resources in China.Based on fluorite properties such as its crystal structure and the color-causing mechanism,the research progress of fluorite flotation technology was described in details.The key technical problems of fluorite separation,such as flotation separation of fluorite and calcite,low temperature flotation reagents,and the influence of ions in pulp,were discussed.Finally,some suggestions and solutions have been proposed with a view to providing new ideas and strategies for efficient development and utilization of fluorite resources in China.
