摘要
介绍云南某低品位硅质胶磷矿的矿石性质,针对此矿石嵌布粒度细,且含硅、镁高的特性,采用"正—反浮选"流程,最终获得磷精矿品位30.05%,回收率78.18%,磷精矿含MgO 0.79%、SiO_2 16.97%的指标。
Mineral property of low-grade siliceous phosphate ore in Yunnan province is described in this paper. Since the ore is finely embedded, and contains high silicon, magnesium, experiments are conducted using direct-reverse flotation. The final grade of the phosphorus concentrate is 30. 05% , including MgO 0. 79% and SiO2 16.97%, at recovery of 78. 18% P2O5..
