Method for comprehensively using vanadium-titanium magnetite by shaft furnace reduction and electric furnace melting

The invention discloses a method for comprehensively using vanadium-titanium magnetite by shaft furnace reduction and electric furnace melting, characterized by: mixing vanadium-titanium magnetite concentrates with a binder to prepare oxidized pellets, reducing in a gas base shaft furnace at 900-1200 DEG C under the pressure of 0.2-0.3Mpa for 4-6 h, wherein the content of the reducing gas that is a mixture of H2 and CO is no less than 90%, and the molar ratio of H2 to CO is 1-3; putting the reduction product into the electric furnace for melting and conducting slag-iron separation to obtain molten iron and slag, wherein the slag contains vanadium-titanium and is used for vanadium extraction and titanium extraction. According to the invention, effectively extraction and utilization of titanium can be realized; there is no need for coke and no coking coal is consumed, thus the increasing insufficiency of coking coal resource is alleviated.
