The invention relates to a method for comprehensive utilization of
vanadium-
titanium magnetite, which belongs to the field of new technology of direct reduction ironmaking in the
metallurgical industry. In order to solve the problems of low utilization of iron,
vanadium and
titanium in
vanadium-
titanium magnetite, at the same time, due to the
sintering process of traditional technology, the comprehensive
energy consumption of the overall
smelting process is relatively high, and the environmental
pollution is serious. The invention provides a method of agglomerating vanadium-titanium
magnetite and producing high-
titanium slag and pearl iron by high-temperature reduction and melting in a rotary
hearth furnace. The technical solution includes
pelletizing of vanadium-titanium magnetite, high-temperature reduction in rotary
hearth furnace,
magnetic separation, and high-temperature reduction in rotary
hearth furnace to directly produce high-
titanium slag and pearl iron. Applying this method to process vanadium-titanium magnetite can not only effectively solve the problem of
recovery of titanium and vanadium resources, but also obtain qualified iron pearls for
steelmaking in
electric furnaces, making full use of the iron, vanadium, and Valuable elements such as titanium.
