Abstract Vanadium titanomagnetite (VTM) is a complex polymetallic symbiotic mineral dominated by iron, titanium, and vanadium. Iron extraction from VTM is an issue for the utilization of Vanadium titanomagnetite concentrate. In this work, flotation method combined with magnetic sorting was proposed to separate and recover the iron resources from VTM. The …
