| 摘 要： | 采用充填浮选柱通过正-反两段流程柱式分选云南某中低品位磷矿,考察了磨矿时间、药剂用量等工艺条件对分选指标的影响.结果表明,通过柱式短流程分选可以获得P2O5品位32.79％、回收率82.92％、MgO质量分数0.42％的精矿,且药剂用量与机械搅拌浮选机所用有差别. |
| 关 键 词： | 中低品位磷矿 充填浮选柱 正-反浮选 |

| Abstract: | Mid-low grade phosphate rock from Yunnan province was separated in the packed floatation column by direct-reverse flotation.The effect of grinding time,dosage of flotation reagents and other parameters on flotation indices was investigated.The results indicated that phosphate concentrate containing P2O5 32.79%,MgO 0.42%with P2O5 recovery of 82.92%was obtained by short flowsheet separation in packed floatation column,and the flotation reagent dosages were different from mechanical agitation flotation machine. |
| Keywords: | mid-low grade phosphate rock packed flotation column direct-reverse flotation |
