| 摘 要： | 通过偏光显微镜、扫描电镜、能谱仪和电子探针的分析手段,对攀钢钒工业生产钒渣中钒尖晶石的结构与构造、化学组成及变化规律等进行详细的矿物学特征研究。结果表明,焙烧过程中氧化的钒尖晶石结构逐渐变的疏松多孔,构造上由单一的钒尖晶石向铁板钛矿固溶体、氧化铁固溶体和钒酸锰固溶体转变;钒尖晶石的化学成分主要有镁、铝、钛、钒、锰、铁等元素组成。随着氧化程度的深入,Fe O的含量在逐渐增加,V2O3的含量在逐渐减少,其他元素含量的变化不大。

| 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 . |
