The titanium recovery process of an investigated plant is high-intensity magnetic gravity separation (spiral). Due to the limitation of the spiral concentrator on the particle size of ilmenite, the recovery of coarse ilmenite is better, and the recovery of fine ilmenite and ilmenite intergrowth is poor. The recovery of titanium in iron tailings is only 25.3%. In order to recover titanium resources effectively, experiments of high-intensity magnetic and flotation conditions were carried out. The results show that after further fine grinding and iron removal by weak magnetic field, the −200 mesh (74 µm) test sample (about 84% in proportion) of ultrafine grade titanium separation raw material was obtained, after the combined process of “two-stage strong magnetic + flotation”, the finally obtained titanium concentrate TiO2 grade is 46.86%, the total yield of process concentrate is 5.93%, and the total recovery of process concentrate TiO2 is 25.84%.
