摘　　要：独居石与氟碳铈矿浮选分离新工艺的研究表明,以单烷基磷酸酯(P538)作捕收剂,柠檬酸作调整剂,能有效地使独居石与氟碳铈矿浮选分离。人工混合矿的浮选分离和白云鄂博混合稀土精矿的验证试验都获得了良好的结果。通过各种现代测试手段研究柠檬酸在这两种矿物表面的作用及其作用后两种矿物的表面性质的差別,提出了柠檬酸在独居石和氟碳铈矿浮选分离中抑制氟碳铈矿的作用机理。In this paper a new technique for separating monazite from bastnaesite by flotation is described. The results show that the separation of monazite from bastnaesite can be effectively realized with mono-alkyl ester phosphoric acid as a collector and citric acid as a regulato(?). The test results of separating an artificial mixture and the bulk concentrates of monazite and bastnaesitc from Baiyun-Ebo ore are satisfactory. The effect of citric acid on the surface of two rareearth minerals and the difference in...
