Abstract:The sintering basic characteristics of five typical vanadium titanium magnetite with large domestic usage were systematically studied by micro-sintering equipment. The phase composition of vanadium titanium magnetite concentrate was analyzed by XRD analysis and SEM-EDS analysis. The results show that the sintering basic characteristics of vanadium titanium magnetite are closely related to its chemical composition and phase composition. The main phase of low-titanium vanadium titanium magnetite is magnetite, and the comprehensive evaluation index of sintering basic characteristics is relatively better, of which CJ is the best. However, the main phase of high-titanium vanadium titanium magnetite is magnetite and ilmenite, their basic characteristics are very poor, which is mainly affected by titanium. On the whole, the vanadium titanium magnetite has a poor sintering basic characteristics and should be matched with iron concentrate with better basic characteristics as much as possible.
