摘　　要：尾渣的二次资源化利用对缓解资源紧张、矿业可持续发展具有十分重要的意义。秘鲁某选铁尾渣量大,含有较高的Cu、Co、S等有价元素,其金属矿物在海水富离子介质条件下受溶解蚀变及上游选厂铁精矿脱硫降锌作业大量浮选药剂深度活化,分离回收难度较大。通过对矿石性质研究,采用阶段磨矿-混合浮选-铜与硫钴分离的工艺,在实验室小型试验的基础上进行半工业调试,取得较好的Cu、Co、S综合回收效果。The secondary resource utilization of tailings is of great significance for relieving resource shortage and sustainable development of mining industry.The tailings of an iron beneficiation in Peru contain a large amount of Cu,Co,S and other valuable elements,and its metal minerals are deeply activated by dissolution alteration under the condition of ion-rich medium in seawater and a large number of flotation agents during desulphurization and zinc reduction of iron concentrate in upstream beneficiation plant,so it is difficult to separate and recover.Through the study of the ore properties,the process of stage grinding,mixed flotation and separation of copper and sulfur cobalt was adopted,and semi-industrial commissioning was carried out on the basis of small laboratory tests,and a good comprehensive recovery effect of Cu,Co and S was obtained.
