Sub-molten salt method has been proved extremely effective as a green metallurgical process for treatment of vanadium-titanium magnetite (S.Zheng et al., 2006).Generally, concentrated alkaline leach solution containing amphoteric metals, such as vanadium (Ⅴ) and chromium (Cr), can be obtained during the process by sub-molten salt leaching.
