摘　　要：针对贵州某P2O5品位11.68%、MgO含量10.87%的钙镁质低品位磷矿石进行了选矿试验研究。结果表明,通过"正浮选、一粗两扫反浮选"闭路流程,获得了P2O5品位28.04%、P2O5回收率81.92%、MgO含量0.75%的磷精矿。Mineral processing experiments were conducted with a lean calcareous-magnesium collophane ore from Guizhou with P2O5 grade of 11.68%and MgO grade of 10.87%.Adopting a closed-circuit flowsheet consisting sequentially of a direct flotation and a reverse flotation with one roughing and two scavenging stages,a phosphorus concentrate with P2O5 grade of 28.04%,MgO content of 0.75%and P2O5 recovery of 81.92%was obtained.
