摘要
黄铜矿和辉钼矿常共伴生于斑岩型矿床中,两种矿物具有极其相近的可浮性,因此铜钼分离一直是矿物加工领域研究的重点和难点。浮选技术是铜钼分离常用的方法,且浮选药剂是控制浮选分离效果的关键。在阐述黄铜矿和辉钼矿的晶体结构、表面润湿性、表面电性等物理化学特性的基础上,分析了两种矿物分离的难点,系统地讨论了铜钼分离的工艺和浮选药剂研究进展,同时对铜钼浮选分离未来的发展方向进行了展望,以期为同行提供借鉴。
Chalcopyrite and molybdenite are often associated in porphyry deposits,and they have very similar floatability.Therefore,the flotation separation between chalcopyrite and molybdenite has become important and difficult points.Flotation technology is a common method for the separation of chalcopyrite and molybdenite,and flotation reagents are critical to control the separation efficiency.Based on the crystal structure,surface wettability,surface electrical properties and other physicochemical properties of chalcopyrite and molybdenite,the separation difficulties were analyzed.In addition,the process of copper-molybdenum separation and the research development of flotation reagents were discussed systematically.The future development of flotation separation of chalcopyrite and molybdenite was prospected.The aim of the paper is to provide references for peers.
