摘　　要：辽宁某含铷铯矿铷品位为0.0494%,通过光片分析、扫描电镜、选矿试验得出结论,该矿石中的铷以类质同象形式替代钾、钠离子富存于黑云母、长石中,本次试验采用磁选-浮选联合成功对该矿石中的云母、长石进行了富集,开路试验结果表明,原矿中云母含量较低,试验结果表明,云母精矿产率为1.21%,云母精矿中铷品位为0.2647%。长石精矿浮选作业回收率为32.35%,长石精矿中铷品位为0.0678%。云母中的铷可以采用其他化学选矿的方法进一步富集,长石精矿中的伴生铷进一步提纯较为困难,因此该长石精矿应作为长石合格品于玻璃等其他工业产业中应用。A rubidium-cesium containing ore in Liaoning Province has a rubidium grade of 0.0494%.Through optical analysis,scanning electron microscopy,and beneficiation tests,it is concluded that the rubidium in the ore replaces potassium and sodium ions in biotite and feldspar in isomorphic form.In this test,the combination of magnetic separation and flotation was used to successfully enrich the mica and feldspar in the ore.The results of the open circuit test showed that the mica content in the raw ore was low.The test results showed that the mica concentrate yield was 1.21%,The rubidium grade in mica concentrate is 0.2647%.The flotation recovery rate of feldspar concentrate is 32.35%,and the rubidium grade of feldspar concentrate is 0.0678%.The rubidium in mica can be further enriched by other chemical beneficiation methods.It is more difficult to further purify the associated rubidium in the feldspar concentrate.Therefore,the feldspar concentrate should be used as a qualified product of feldspar in glass and other industrial industries.
