For scheelite, fluorite, calcite have similar surface properties and floatability, it is difficult to achieve efficient recovery of scheelite in the flotation system. Therefore, it is essential to develop effective separation depressants for calcium-bearing gangue minerals and scheelite flotation collectors. Based on the survey on the research status of separation depressants for calcium-bearing gangue minerals and scheelite flotation collectors, this paper elaborated on the mechanisms and applications of a variety of inorganic depressants and organic depressants. In accordance with the current research progress of depressants on calcium mineral calcium mineral and scheelite, this paper suggested that the hydrophilic improvement of inhibitor can greatly improves its selectiveness.%白钨矿与萤石、方解石等含钙矿物表面性质相似,可浮性相近,在浮选体系中难以实现白钨矿与它们的高效分离和有效回收,因此在研究白钨选矿浮选捕收剂的同时,开展对含钙脉石矿物高效分离抑制剂的研究至关重要.文章综述了近年来白钨矿与含钙脉石矿物分离抑制剂的研究现状,详细阐述了多种无机抑制剂和有机抑制剂的抑制机理和应用,并结合当前白钨矿与含钙矿物抑制剂的研究进展,认为开发对含钙矿物具有高效抑制性能的药剂引入特性基团增强抑制剂的亲水性,能达到提高其选择性的目的,最后探讨了抑制剂研究的新方向.
