摘　　要：为经济合理利用晋宁低品位胶磷矿,将其与昆阳高碳酸盐型胶磷矿配矿后浮选。在昆阳高碳酸盐型胶磷矿与晋宁低品位胶磷矿按质量比4配矿后,经过一粗一精一扫反浮选工业生产获得精矿w(P_(2)O_(5))29.32%、w(MgO)0.88%、产率69.40%、P_(2)O_(5)回收率92.98%,尾矿w(P_(2)O_(5))6.72%的选矿指标。In order to make economic and rational use of Jinning low-grade collophanite,Jinning low-grade collophanite and Kunyang high carbonate collophanite are blended for flotation.By blending Kunyang rock and Jinning rock with mass ratio of 4,the mineral processing indexes of concentrate P_(2)O_(5) content 29.32%,MgO content 0.88%,yield 69.40%,P_(2)O_(5)recovery rate 92.98%and tailings P_(2)O_(5) content 6.72%are obtained in industrial production of one coarse one fine one sweep reverse flotation.
