某Rb2O品位仅为0.048%的低品位铷矿，直接进行氯化焙烧—浸出，可获得合格的氯化 铷产品，为了降低综合加工成本，提高铷资源的开发利用价值，针对该低品位铷矿开展了铷资源选矿 预富集探索试验。试验结果表明：在磨矿细度为-74 μm65%及中性浮选条件下，将十二烷基硫酸钠 与椰油胺按质量配比 1∶1作为组合捕收剂，采用1粗 2扫、粗选与扫选精矿合并再经 1次精选浮选工 艺流程，最终获得了Rb2O品位0.102%、Rb2O回收率60.99%的铷精矿
A low-grade rubidium ore with Rb2O grade of only 0.048% was directly subjected to chlori⁃ nation roasting-leaching to obtain qualified rubidium chloride products. In order to reduce the comprehen⁃ sive processing cost and improve the development and utilization value of rubidium resources，the explora⁃ tion test of beneficiation pre-concentration of rubidium resources was carried out for the low-grade rubidium ore.The test results show that under the condition of grinding fineness of -74 μm 65% and neutral flotation， the mass ratio of sodium dodecyl sulfate to coconut oil amine is 1∶1 as the combined collector，and the rubid⁃ ium concentrate with Rb2O grade of 0.102% and Rb2O recovery of 60.99% is finally obtained by one rough⁃ ing two scavenging，roughing and scavenging concentrate combined one cleaning flotation process.
