Abstract

Abstract

The relationship between crushing strength of pellets and leaching behaviors of vanadium in oxidation roasting-HCl leaching process from high-chromium vanadium-bearing titanomagnetite concentrates were investigated in this work. The results of the thermodynamic analysis of oxidizing roasting process show that the order of reaction of main compounds is: FeTiO₃>Fe₃O₄>Fe₂SiO₄>FeV₂O₄>FeCr₂O₄. The phase analysis results of oxidation roasting process show that the oxidation reaction of the ilmenite is easier to magnetite, and the main phases of oxidation pellets are Fe₂O₃ and Fe₉TiO₁₅. Experimental results indicate that the oxidation temperature and HCl concentration are the key factors affecting the leaching efficiency of vanadium and the crushing strength of leached pellets in the oxidation process and leaching process respectively. There is an obvious negative correlation between the leaching efficiency of vanadium and the crushing strength of leached pellets. The crushing strength of leached pellets can be effectively increased by return roasting process. The crushing strength of pellets after return roasting is greater than 3 000 N/pellet under the condition of roasting temperature of 1 200 ℃ for 90 min, which can be used as raw materials for blast furnace ironmaking.
