摘　　要：对国外某地钒钛磁铁矿贫矿中伴生磷(P2O54.19%)进行了综合回收试验研究。结果表明:采用弱磁选—强磁选—浮选联合工艺流程,不仅能有效选别钛磁铁矿、钛铁矿,还可综合回收该资源中伴生的磷,得到产率为9.85%、品位为36.76%的优质磷精矿。An experimental research on comprehensive recovery of associated apatite from a lean vanadium -containing titanomagnetite ore was carried out. The results showed that using the technological flowsheet of＂low - intensity magnetic separation - high - intensity magnetic separation - flotation＂ , not only the titanomagnetite, ilmenite can be effectively separated, but the associated apatite in the mineral resources can also be satisfaetorily recovered. The high - quality phosphorus concentrate of 36.76% P2O5 with a yield of 9.85% is obtained.
