About 90%rare earth minerals and many other valuable minerals are heaped as iron tailings without comprehensive utilization.In order to comprehensively recover these valuable minerals,in a view of the valuable ore type of Baotou Steel tailing and embedded features,valuable components flow and their respective recovery coupling relationship in beneficiation flowsheet were analyzed;process flows and parameters which could give consideration to four kinds of components were determined.TFe,rare earth oxide(REO),niobium and fluorite recoveries could reach 72.70%,81.84%,78.58%and60.18%in low-intensity/high-intensity magnetic separation,respectively.High-intensity magnetic concentration was treated by REO direct flotation;the recovery is75.43%,on the base of which Fe could be separated completely from Nb.The underflow was treated by reduction roasting-low-intensity magnetic separation.And the relationship between the recoveries of these valuable components was also discussed.
