| Abstract: |
| Through the analysis of polarized light microscopy, scanning electron microscope, energy spectrometer and electron probe, studied structure and tectonics, chemical composition and their variations of vanadium spinels in vanadium slag in Panzhihua Steel Vanadium industrial production. The results show: Vanadium oxide porous spinel structure in the process of roasting gradually,the vanadium spinel transform to ilmenite solid solution, ferric oxide solid solution and vanadate Mn solid solution; The chemical composition of vanadium spinels is consist of Mg, Al, Ti, V, Mn, Fe and other elements. With the oxidation degree of depth, the content of FeO increased, the content of V2O3 decreased gradually . |
