Non-ferrous metal resources such as copper, lead and zinc in the nature are increasingly deficient along with the increase of mining intensity, and how to comprehensively recover the metals from secondary resources such as tailings and tailings is a great trend. Many iron ores contain a small amount of nonferrous metals such as copper, lead and zinc, and the like, and can not meet the recovery standard by separate separation, but after iron separation, the nonferrous metal minerals in the ores form secondary enrichment in iron separation tailings, and part of the nonferrous metal minerals meet the comprehensive recovery standard, but because the properties of the iron separation tailings are relatively complex, the conventional collecting agent is adopted, the recovery rate of the nonferrous metals is generally not high, even qualified concentrate products can not be produced, and the following problems mainly exist:
(1) the iron separation tailings have complex components, primary sulfides, secondary sulfides and oxides coexist, and the floatability of the non-ferrous metal minerals is changed to a certain extent under the action of ore grinding and a magnetic field and by adding a beneficiation reagent in the iron separation process;
(2) in the iron ore dressing tailings, because part of minerals are argillized due to early grinding, the floatability of non-ferrous metal minerals in the tailings is poor, and the floatability of part of easily floating gangue is similar, so that the separation is difficult.
