Optimized magnetic separation for efficient recovery of V and Ti
Effect of magnetic intensity on separation of vanadium, titanium and iron. In this study, magnetic separation was used to obtain high-quality vanadium concentrates from the VTM ore. The production of titanium-rich concentrates to recover titanium was also very important because the VTM ore contains high ilmenite [26, 27]. Therefore, from …
