Abstract	The paper presents the effect of pretreatment on the ammonium sulfate roasting behavior of vanadium-bearing titanomagnetite. The effects of the several parameters included pretreatment temperature, time and atmosphere upon the extraction efficiency of V, Ti and Fe were investigated. Under the conditions of a pretreatment temperature of 900 degrees C, a time of 2h and an air flow of 4 L/min, the extraction efficiency of V, Ti and Fe reached 92.56%, 11.25% and 78.72%, respectively. The study of the valence state changes of V and Fe before and after pretreatment found that pretreatment was beneficial to increase the content of acid soluble V(IV) and V(V), and enrich Ti species. XRD, SEM-EDS and FTIR were deeply clarified the influence of pretreatment on the evolution characteristics of the mineral phase. Additionally, the difficulty of pyrolysis between the intermediate Ti species and ammonium sulfate was analyzed by thermodynamic simulation.
