The effect of (CaO + SiO2) mass ratio on high-Ti vanadium titanomagnetite sintering was systematically studied at the fixed basicity (CaO/SiO2) of 2.0. The results show that sinter matrix strength is improved with (CaO + SiO2) mass ratio while the total iron content is reduced. Thermodynamic analysis indicates that the increase in (CaO + SiO2) mass ratio from …

Vanadium recovery was dependent on maximizing magnetite and ilmenite recovery. Ilmenite, which is the main source for titanium, existed in the stripes within magnetite; it got pulverized first during milling and remained as relatively coarse particles of magnetite.
