摘　　要：对辽宁北票低品位磷灰石型磷矿进行了选矿实验研究。原矿经粗磨后,采用SA-6A作为捕收剂,碳酸钠和水玻璃作为调整剂,开路试验获得的磷精矿P2O5品位为34.04%,P2O5回收率为57.46%。闭路流程试验获得了精矿P2O5品位为34.05%,P2O5回收率为93.66%的浮选指标。选磷尾矿经再磨后,在磁选强度为1.2N/A·m的条件下,开路流程试验获得的铁精矿TFe品位为65.59%,TFe回收率为43.33%的磁选指标。The experimental study on beneficiation of a low-grade apatite phosphate ore from Beipiao area in Liaoning was carried out.After rough grinding process,with SA-6A as collector and sodium carbonate and sodium silicate as regulators,a phosphate concentrate with P2O5 grade of 34.04%and recovery of 57.46%was obtained from the open-circuit test,while a phosphate concentrate with P2O5 grade of 34.05%and recovery of 93.66%,was obtained from the closed-circuit test.Then after regrinding process of the phosphate tailings,with the intensity of magnetic separation of 1.2 T,an iron concentrate with TFe grade of 65.59%and recovery of 43.33%was obtained from the open-circuit test.
