Research status and development prospect of utilization of vanadium titanium magnetite

As a special mineral resource rich in iron, vanadium and titanium, vanadium titanium magnetite has high comprehensive utilization value. The research status of vanadium titanium magnetite processing and utilization was discussed from the beneficiation of vanadium titanium magnetite and metallurgical separation of vanadium titanium magnetite concentrate. In the aspect of mineral processing, the development of new beneficiation equipment and reagents, and optimization of beneficiation processes are to obtain qualified vanadium titanium magnetite concentrates. In addition, the reasons why it is difficult to further improve the beneficiation index were also explained in this part. In the aspect of metallurgical separation, the reason why the non blast furnace method cannot achieve industrial production was explained by analyzing and comparing the research status and advantages and disadvantages of each process. Furthermore, it was considered that the fluidized pre reduction electric furnace melting method is an important research direction to realize the efficient utilization of vanadium titanium magnetite concentrate in the future.
