| 摘 要： | 云南某磷矿擦洗矿泥P2O5含量达20.08%，主要含磷矿物为氟磷灰石，矿物粒度粗细不均，磷在粗粒级有一定程度的富集。对试样进行了回收磷的浮选试验。结果表明，在磨矿细度为-200目占70%时，以自制的LC3为磷矿物捕收剂，采用2粗2扫3精、中矿顺序返回流程处理该擦洗矿泥，最终可获得P2O5品位为28.38%、回收率为98.67%的磷精矿。

| Abstract: | The scrubbed slime in a Yunnan phosphate mine contains P2O5 of 20.08%，where the phosphorus-containing mineral is mainly fluorapatite with uneven grain fineness. Phosphorus has a certain degree of enrichment in coarse size.Carried out the flotation test to recovery phosphorus，the results showed that under the grinding fineness of 70% -200 mesh and self-developed LC3 as collector of phosphate，phosphate concentrate with P2O5 grade of 28.38 % and a recovery of 98.67% was obtained by the process of two roughings- two scavengings-3 cleanings with the middlings returned into the flows orderly. |
