Abstract

Abstract

For a severely weathered and oxidized V-Ti iron ore from abroad, Fe minerals and Ti minerals are disseminated closely to each other thus it is difficult to separate by physical beneficiation. Based on the specific magnetization coefficient and specific gravity, gangue minerals are quite different from those of metal minerals and are easy to dissociate by grinding, the study on primary enrichment of V-Ti-Fe was carried out. Recovery of V-Ti-Fe by magnetic separation, classification–magnetic separation and gravity separation were compared. The result shows that the magnetic separation is the most suitable method for the ore. The saleable V-bearing iron concentrate consisting of Fe 60.52%, V₂O₅ 1.03% with the recovery of Fe 8.12%, V₂O₅ 8.62%, and the V-Ti-Fe bulk concentrate consisting of Fe 50.03%, V₂O₅ 0.80%, TiO₂ 16.01% with the recovery of Fe 78.61%, V₂O₅ 78.45%, TiO₂ 82.88% were obtained by magnetic separation. The bulk concentrate with high grade of V₂O₅ and TiO₂ could be used as raw materials for extracting vanadium, titanium and iron.
