摘　　要：以验证稀土矿再精选工业化可行性为目的,通过采用XFLB型微型连续闭路浮选机进行一粗三扫三精的连续闭路试验方法,讨论了浮选时间、药剂加入量、浮选充气量、浮选机叶轮转速等因素对选矿指标和分选效率的影响规律,并根据原料矿物特殊性质对浮选时间修正系数进行了调整。实验结果:在流程稳定后,最终获得品位≥65%,回收率≥92%的稀土精矿。In order to verity the feasibility of rare earth concentrate reconcentration industrialization,a test of one rough three scavengers and three cleaners closed-circuit was processed by XFLB micro closed-circuit flotation machine. The experiment schedules were designed as follows： The influence of flotation time,pharmaceutical dosage, inflating volume and impeller speed on mineral separation efficiency indicators was studied and discussed. And according to the special nature of raw mineral,the correction coefficient of flotation time was adjusted. Results： After a stable flow,the rare earth concentrates（ grade≥65%,recovery≥92%） was obtained ultimately.
