Abstract

Abstract

A vanadium-bearing titanomagnetite dressing tailing in Panxi region contents of 8.25% TiO₂. In the ore, the main valuable mineral was ilmenite, and the main gangue minerals were augite and hornblende, and the gangue minerals are of stronger magnetism. Both the particle size and disseminated grain size of ilmenite are relatively fine in the ore, the fine fraction of −38 μm reaches 45.46% and contributes 49.79% TiO₂. In order to utilize the titanium resources effectively, a dressing test for recovering ilmenite was carried out. In this paper, the ore was graded into two parts by particle size after the strong magnetite minerals were removed by a drum magnetic separator, then the coarse-grained ore was separated by using spiral chute and the fine-grained ore was separated by using a ZQS high-gradient magnetic separator. A comprehensive ilmenite concentrate with a yield rate of 36.45%, a TiO₂ grade of 15.88% and a recovery of 70.11% was obtained. Sulfuric acid and sodium silicate were used as regulators and YTB-1 as a collector to separate ilmenite from the comprehensive concentrate which was desulphurized by flotation beforehand. After one rougher stage, four finer stages, and one scavenging stage, the medium ore are returned in sequence, and finally, an ilmenite concentrate with a yield of 9.57%, a TiO₂ grade of 47.23% and a recovery of 54.79% was obtained. Ilmenite mineral resource was recovered effectively.
