    Vanadium-titano magnetite (VTM) is a typical resource in China. The typical method used to recover valuable elements from VTM concentrates is by the blast furnace smelting method. However, titanium is nearly all wasted in the form of blast furnace slag. A new pathway towards obtaining TiO2-enriched material for titanium extraction was designed in this study.
