Abstract

Abstract

By X-ray diffraction (XRD) and scanning electron microscopy (SEM),the process mineralogy of modified and unmodified extracted vanadium tailings,especially the influences of mineralogical characteristics of iron (Fe) and vanadium (V) on the reduction,were studied in this paper. The effects of carbon content,reaction temperature and time on the reduction were systematically investigated.Resultsshow that the metallization rate of Fe reaches to 91.86% under the optimum conditions of 25% carbon content,reaction temperature of 1 150 ℃ and reaction time of 2 h,which lays the foundation for the following smelting separation by arc furnace.
- extracted vanadium tailings,
- mineralogy,
- direct reduction,
- metallization rate
