Additionally, the additive (NH 4) 2SO 4 could be recycled, achieving zero emission of waste gas. A high-titanium slag with 85.32% titanium was obtained by the iron powder induction leaching and alkali leaching. XRD and SEM–EDS show that the addition of K 2S 2O 7 strongly promoted the formation of liquid phase and soluble potassium vanadate. Phase transformation and thermodynamic analysis reveals that the valuable metals could be converted into corresponding sulfates in situ. The result shows that 95.87% of vanadium and 80.13% of iron could be extracted, while that of titanium was only 9.68% under the condition of first-order temperature and time 240 ☌ and 3 h, second-order temperature and time 410 ☌ and 2 h, and the mass ratio of K 2S 2O 7, (NH 4) 2SO 4 and PVBT 0.1:4:1. In this study, an efficient utilization of vanadium titanomagnetite concentrate was systemically investigated through potassium pyrosulfate (K 2S 2O 7) synergized with ammonium sulfate ((NH 4) 2SO 4) cascade roasting to separate and recover vanadium, iron, and titanium. ![]()
