摘　　要：对湖北某地镁硅含量较高的难选胶磷矿采用阴离子捕收剂反浮镁、阳离子捕收剂反浮硅的双反浮选工艺,取得了磷精矿P2O5品位32.51%、回收率91.23%、MgO含量0.87%、R2O3含量2.37%的良好指标,实现了胶磷矿与白云石、长石等杂质矿物的有效分离。Double reverse flotation process of adopting anion collector to flotate magnesium and adopting cation collector to flotate silicon was used to separate phosphate rock with high content of magnesium and silicon. The phosphate concentrate with P2O5 32.51%, recovery 91.23%, MgO 0.87%, R2O3 2.37% was obtained.
