Abstract
In order to better develop and utilize the low-grade vanadiferous titanomagnetite concentrate with high titanium (LVCHT) and provide reference for the treatment of similar minerals. Oxidation process and kinetics of the LVCHT were investigated in this study. The results show that LVCHT presents weight loss at temperatures less than 600 °C, which is attributed to the removal of moisture and volatile components. Above 600 °C, the weight gain of LVCHT is due to the persistence of oxidative behavior, and the oxidation process is most likely controlled by external diffusion, and the associated activation energies (Ea) and the value of k 0 are 29.89 kJ/mol and 0.64, respectively.
