摘　　要：钨细泥中矿物粒度小、比表面积大、表面能高、矿物组成复杂,传统的单一浮选、重选、磁选工艺难以有效回收钨细泥资源,造成资源浪费。加强对钨细泥选矿回收工艺研究意义重大。随着工艺、设备、药剂的不断发展,重、磁、浮等多种选别方法相结合的联合工艺流程日趋成熟。文章介绍了不同性质的钨细泥常采用的选别工艺发展现状并指出加强对钨细泥性质的研究,采用多种工艺联合流程,同时加强对伴生金属的回收是钨细泥选别技术的重要发展方向。Due to the small particle size,large specific surface area,high surface energy and complex mineral composition of tungsten fine mud,it is difficult for the traditional single flotation,gravity and magnetic separation technology to effectively recover tungsten fine mud resources,which results in a waste of resources.It is of great significance to strengthen the research on beneficiation technology of tungsten fine mud.With the continuous development of technology,equipment and reagents,the combined process of gravity,magnetic and floating separation methods is becoming more and more mature.This paper introduces the development status of the separation technology of tungsten slime with different properties and points out that it is important to strengthen the research on the properties of tungsten slime to adopt a combination of various processes.At the same time,to strengthen the recovery of the associated metals is an important development direction of tungsten fine sludge separation technology.
