Abstract
The tailings after titanomagnetite recovery from a vanadic titanomagnetite ore contain 13. 93% TiO2, belonging to the ore of high - vanadium - bearing type, the ore composition is very complex, ilmenite, titanomagnetite as the main metal minerals and pyroxene, plagioclase and oli-vine as the main gangue minerals. According to the properties of the tailings, a combined technological flowsheet of high - intensity separation - flotation was adopted. After a discarding of tailings by high - intensity magnetic separation, through one rougher flotation, three cleaning and three scavenging, the qualified titanium concentrate containing 48. 87% TiO2 with a recovery of 68.97% is obtained. The beneficiation index is satisfactory and the comprehensive recovery and utilization is realized.关键词
