Experimental Study on Flotation of the Fine Ilmenite with a New Collector TZ-1

In this paper, two new chelating agents were compared with three ilmenite conventional chelating agents, and it was found that the new chelating agents had more advantages in selective collection. In order to solve the problem of low recovery of fine ilmenite in a plant Panzhihua–Xichang area, a new collector TZ-1 was prepared by combining the new chelating agent and oleic acid soap. The test results show that for the fine ilmenite raw ore with the content of -0.023 mm particles as high as 88% and TiO₂ grade of 15.85%, the new TZ-1 collector is used with sulfuric acid and sodium silicate. After the closed-circuit test of desulphurization, one rough, one sweep and four fine, TiO₂ grade of 47.29% is finally obtained. Titanium concentrate with 58.41% recovery. The results show that the new collector TZ-1 can effectively solve the problem of low recovery of fine ilmenite in the plant, and has guiding significance for the efficient recovery and utilization of ultrafine ilmenite.
