This is a paper in the field of mineral processing engineering.With the continuous development of mineral processing technology and the improvement of the degree of attention to mineral resources, more and more researches on the comprehensive utilization of tailings have been carried out. Chemical multivariate analysis, SEM and other techniques were used to characterize the copper ore in a vanadium titanomagnetite iron tailings, the study shows that the main valence element is copper, and mainly exists in the form of copper sulfide. A vanadium-titanium magnetite tailings in Hebei was used as a research object. Using butyl xanthate, A8 and MK305 for flotation recovery of copper in iron tailings, it is determined that the optimum flotation technical index is obtained when the A8∶MK305 dosage ratio is 1∶1 and the crude collector dosage is 45 g/t, 2# oil is 7.5 g/t, through single collector test, combined collector test, collector dosage test and 2#oil dosage test. The results of closed circuit test show that the
