Abstract:In the flotation of ilmenite, the surface modification can increase the difference of surface properties between minerals, which is the key to the efficient flotation separation of ilmenite. In this paper, the effects of surface modification methods, such as flotation reagents, surface dissolution, external position control, oxidation roasting and oxidant modification, on mineral flotation behavior were summarized. The advantages and disadvantages of collectors, inhibitors and activators in the flotation of ilmenite were summarized, the differences and common points of various surface modification methods were compared, and the main problems and solutions in the flotation process of ilmenite were proposed, so as to provide reference for the efficient separation of ilmenite.
Key words: ilmenite; flotation; flotation reagent; surface modification
