摘　　要：本文对某残坡积型稀土矿石进行了浮选试验研究,结果表明浮选工艺能获得好的选别指标,一粗一扫一精浮选闭路试验,可获得了稀土品位15.34%,回收率75.22%的稀土精矿。In this study, a mineral processing technology has been studied for a residual deluvial rare earth ore. The re- sult indicates that the REO concentrate with grade 15.34% and recovery 75.22% can be achieved by adopting a closed flota- tion flowsheet with one roughing, one cleaning and one scavenging.
