Abstract

Abstract

In this paper, the optimization test of ilmenite flotation reagents was carried out for an iron dressing tailing in Panxi. With a TiO₂ grade of 16.6%, this tailing is mainly composed of ilmenite, titanomagnetite, pyroxene and olivine, and the secondary minerals are plagioclase and chlorite. The types and dosages of collectors, inhibitors and sulfuric acid were optimized. Using the combination of sulfuric acid, EMA and MOH, a five-time titanium concentration process was obtained, including iron removal by magnetic separation, flotation desulfurization, one rough selection and one sweep selection. Under the optimal conditions, a good index of titanium concentrate yield of 25.18%, TiO₂ grade of 46.48% and recovery of 71.31% can be obtained in the closed circuit test, which provides a technical reference for the recovery of ilmenite from iron separation tailings in Panxi mining area.
