| Abstract: |
| Pan-xi vanadic titanomagnetite is the most important strategic resources including iron, vanadium and titanium in China. After many years" research and innovation, those resources have formed complete industry chain covering from ore mining, ore dressing and smelting. However, some key technical difficulties such as lower resource utilization efficiency, some valuable mineral unutilized and so on are still unresolved. Currently, the resource utilization of iron, vanadium and titanium are merely 70%、41% and 21%, respectively. Moreover, precious metals like Co, Ni, Cr and Sc are still unutilized., According to the mineralogical properties of Pan-xi vanadic titanomagnetite, the current status and development of ore dressing engineering are reviewed in this paper. The results show that iron concentrate and tailings from iron ore dressing could be obtained from the vanadic titanomagnetite using the process of the stage-grinding and stage separation. Then ilmenite concentrate has been isolated from the tailings through the technological processes including high gradient high intensity magnetic separation, gravimetric concentration, flotation, and electric separation. V and Cr are present mainly as isomorphism in iron concentrate. Pan-xi vanadic titanomagnetite could be become a green and efficient comprehensive utilization through optimizing and developing new mineral processing. |
