| 摘 要： | 为了清洁、高效且低成本开发刚果(金)某含钴0.606%、铜1.45%的钴矿产资源，针对该矿赋存状态复杂、含泥量高等问题，采用新型活化浮选-磁选联合工艺流程，最终获得的综合精矿钴品位为1.627%、钴回收率为74.34%，铜品位为4.71%，铜回收率为88.14%。该工艺与常规硫化黄药法相比，具有流程稳定、适应性强、操作简便等特点，可为刚果(金)同类矿石资源的选矿工艺提供借鉴和参考。

| Abstract: | To clean,efficient and low-cost develop a cobalt mineral resources in Congo (gold),which containing 0.606% cobalt,1.45% copper,a new activation flotation-magnetic separation combined process was conducted for complex dissemination and high smud of the ore.The final comprehensive concentrate index with cobalt grade of 1.627% and recovery of 74.34%,copper grade of 4.71% and recovery rate of 88.14% was obtained.Compared with conventional xanthate sulfide method,the process has stable process,well adaptability and simple operation,which can provide reference for the processing technology of similar mineral resources in Congo (gold). |
