摘　　要：铜钼硫化矿常常紧密共生且可浮性相近,二者的浮选分离一直是选矿研究的重点。铜钼矿石一般采用浮选方法进行分离,铜钼混合浮选—铜钼分离是目前工业上应用最为广泛的工艺,在混合浮选之后,通常先进行预处理,尽可能脱除铜钼混合精矿中的浮选药剂以及矿物表面残余的药剂,为铜钼分离提供条件。本文将铜钼分离预处理工艺分为三大类:一是解吸脱药法,二是机械脱药法,三是矿物表面的氧化处理。前两种是目前比较常用的预处理脱药方法,但仍存在着流程复杂、有污染等特点,而矿物表面的氧化处理除了可以达到脱药的目的,还可以实现铜矿物的表面氧化,增大铜钼的可浮性差异。铜钼混合精矿浮选分离预处理工艺研究对改善铜钼混合精矿的分选效果具有重要意义。Cu−Mo sulfide ores are often closely associated with each other and have similar floatability.Their flotation separation has always been the focus of research.Copper−molybdenum ore is generally separated by flotation method.The technology of Copper−molybdenum mixed flotation−copper−molybdenum separation is the most widely used process in the industry at present,after bulk flotation,usually the first pretreatment process,as far as possible to remove the flotation agents in copper−molybdenum bulk concentrate and desorption of residual agents from mineral surface,to provide conditions for copper−molybdenum separation.In this paper,the copper molybdenum separation pretreatment process is divided into three categories,one is desorption reagent removal method,the second is mechanical reagent removal method,and the third is the oxidation treatment of mineral surface.The first two are currently more commonly used pretreatment regent removal methods,but there are still complex processes,pollution and other characteristics,the oxidation treatment of mineral surface in addition to the purpose of reagent removal,but also to achieve the surface oxidation of copper minerals,increase floatability difference between copper and molybdenum minerals.Through the research and technical summary of flotation separation pretreatment technology of copper−molybdenum mixed concentrate,it is of great significance to improve the separation effect of copper−molybdenum mixed concentrate.
