The vanadium-titanium magnetite resources in Hami area of Xinjiang are abundant; utilizing this kind of magnetite for pellet production holds significant theoretical and practical value for promoting green transformation of the iron and steel industry. In this study， the vanadium-titanium magnetite from Hami area of Xinjiang was studied on the effects of preheating and roasting conditions to the properties of pellets of vanadium-titanium magnetite and XRD and SEM-EDS was used to detect and analyze its phase composition and microstructure， thereby revealing the consolidation mechanism of the pellets of vanadium-titanium magnetite during oxidizing roasting. The results indicate that the optimal process conditions for the pellets of such vanadium-titanium magnetite are preheating at 900 ℃ for 18 min followed by roasting at 1 250 ℃ for 12 min，under which the roasted pellets achieve a compressive strength of 2 579.61 N/P. The oxidation consolidation process can be divided into three stages: In the initial stage of oxidation，magnetite and titanium magnetite undergo oxidation, resulting in large pores and loosely distributed particles with low compressive strength. In the intermediate stage of oxidation，magnetite and titanium magnetite further undergo oxidation to generate hematite and ferrous titanate，while ilmenite reacts with hematite to generate haplotypite，reducing the porosity and densifying the pellet structure. In the final stage，hematite recrystallizes well and aggregates into larger particles， forming a highly compact structure among particles，essentially completing the oxidation consolidation and significantly enhancing compressive strength of pellets. The findings of this study provide a basis for the application of vanadium-titanium magnetite in pellet production process.
