| Abstract: | Based on the carbon thermodynamic analysis, experiments of pellet reduction-roasting of vanadium tailings are conducted. With phase and component analysis, carbon thermal reduction process of metal oxide in vanadium tailings is systematically studied. The results indicate that under different reduction temperatures, reduction process of iron, chromium, vanadium, manganese and titanium exhibit different characteristics and transfer rules. |
