The invention discloses a method for recycling ilmenite from vanadium titano-magnetite iron dressing tailings. The method comprises the steps that the specific susceptibility of main gangue in the iron dressing tailings, the specific susceptibility of the ilmenite in the iron dressing tailings and the content of TiO2 in the iron dressing tailings are determined; when the iron dressing tailings meet the condition 1, the iron dressing tailings are subjected to first-section strong magnetic separation, first-section strong magnetism concentrates are subjected to one-time or multi-time reselection, and gravity concentrates are obtained; the gravity concentrates are subjected to first-time flotation and one-time or multi-time electric separation, and ilmenite concentrates are obtained, wherein the condition 1 can be shown in the formula: X1>(X2*60%), the total amount of the iron dressing tailings serves as a standard, the content of the TiO2 in the iron dressing tailings is lower than 5 wt%, X1 is the specific susceptibility value of the main gangue in the iron dressing tailings, and X2 is the specific susceptibility value of the ilmenite in the iron dressing tailings; and otherwise, the iron dressing tailings are subjected to a strict granularity classification method. By mean of the method, the production cost of the ilmenite is reduced, and the grade of the TiO2 of selected raw ore obtained after electric separation and flotation is improved.
