摘　　要：主要探讨了白钨矿浮选中捕收剂与抑制剂的研究进展。了解白钨矿及其脉石矿物的晶体化学特性以及矿物表面与药剂的相互作用,有助于设计和选择合适的浮选药剂。不同种类的脉石矿物要求精确选择抑制剂,以阻止其浮选上浮,同时尽可能使白钨矿的回收率和品位提高。最新的研究已经涉及到新型抑制剂的配方,利用对水玻璃的表面改性技术和小分子、大分子抑制剂来提高对脉石矿物的选择性。此外,捕收剂和抑制剂之间的相互作用已经成为优化浮选工艺的焦点。这些试剂之间的协同作用或拮抗作用凸显了浮选系统的复杂性。综述了捕收剂和抑制剂在白钨矿及其脉石中提钨的应用。在深入分析捕收剂与抑制剂各自的利弊之后,提出了未来可能的研究方向,为白钨矿选矿药剂的构思与制备提供了方向性的建议,为有效地促进难加工钨矿资源的高效率和环保型开发利用提供一定的借鉴。This review mainly focused on the research progress of collectors and depressants in scheelite flotation.Understanding the crystal chemical properties of scheelite and its gangue minerals,as well as the interaction between mineral surface and reagents is helpful to design and select suitable flotation reagents.Different types of gangue minerals require precise selection of depressant to prevent their flotation,while maximizing the recovery and grade of scheelite as much as possible.Recent research has involved the formulation of novel depressants,using surface modification techniques for water glass and small and large molecule depressant grades to improve the selectivity of gangue minerals.Furthermore,the interaction between collectors and depressants has emerged as a focal point in optimizing the flotation process.The synergistic or antagonistic effects between these reagents highlight the complexity of flotation systems.This article reviewed the application of collectors and depressants in extracting tungsten from scheelite and its gangue minerals.After in-depth analysis of the respective advantages and disadvantages of the collectors and depressants,the possible future research directions were proposed to provide directional suggestions for the conception and preparation of scheelite beneficiation reagents,and provides a certain reference for effectively promoting the efficient and environmentally friendly development and utilization of refractory tungsten resources.
