摘　　要：通过强磁选—反浮选试验,考察了自行研制的QD系列阴离子捕收剂对鄂西高磷鲕状赤铁矿的反浮选效果。试验结果显示:在-0.074 mm占90%的磨矿细度下,QD系列的3种捕收剂均可以从铁品位为47.87%,P含量为0.78%的强磁选精矿获得铁品位大于52%,磷含量小于0.60%,作业铁回收率大于53%的反浮选铁精矿,其中QD-02和QD-03的作业铁回收率大于70%,QD-01可将铁精矿磷含量降至0.46%。试验结果证明QD系列阴离子捕收剂是高磷鲕状赤铁矿的有效反浮选药剂。Through the high intensity magnetic separation- reserve flotation test, the effects of the QD series anionic collector on high phosphorus oolitic hematite ore in western Hubei are investigated. The results showed that under the grind- ing fineness of -0. 074 mm 90%, the reserve flotation Fe concentrate grading at 52% with P content of less than 0.06%, Fe recovery of over 53% was obtained from the HIMS ＇concentrate grading at 47.87% with P content of 0.78% with three kinds of QD-series collectors. Among them, the TFe recovery can be more than 70% with QD-02 and QD-03, and QD-01 collector can decrease P content to 0.46%. The tests are proved that QD-series anionic collectors are an effective reserve flotation agent for high phosphorus oolitic hematite.
