摘　　要：黄铜矿作为关键的硫化铜矿物,在自然界中常与黄铁矿紧密共生。鉴于这2种矿物的浮选特性极为相似,在浮选过程中实现二者的有效分离具有一定难度。综述了黄铜矿与黄铁矿表面浮选特性的差异,总结了多种硫化铜矿浮选技术,包括优先浮选法、混合浮选法、快速浮选法、异步浮选法及分支浮选法等,并阐述了各自具有的独特技术特点,探讨了铜硫浮选分离过程中捕收剂与抑制剂的研究现状,使相关作用机理逐渐清晰。同时,对铜硫浮选分离技术与药剂研发的发展方向进行了展望,以期为铜硫浮选分离研究提供理论基础和实践指导。Chalcopyrite,a critical copper sulfide mineral,often coexists closely with pyrite in nature.Given their highly similar flotation characteristics,achieving effective separation during flotation poses significant challenges.This study reviews the surface flotation characteristic differences between chalcopyrite and pyrite and summarizes various flotation techniques for copper sulfide ores,including preferential flotation,bulk flotation,fast flotation,asynchronous flotation,and branched flotation,highlighting their unique technical features.The current research progress on collectors and depressants in copper-sulfur separation is discussed,revealing an increasingly clear understanding of their mechanisms of action.Additionally,flotation the development directions for copper-sulfur flotation separation technology and reagents are explored to provide theoretical foundations and practical guidance for the study of copper-sulfur flotation separation.
