Method for improving recovery rate of iron component in steel slag

The invention discloses a method for improving the recovery rate of an iron component in steel slag. The method comprises the steps of: mixing modifiers in a predetermined proportion in the steel slag in a molten state, that is, in a process of discharging the molten steel slag, adding the modifiers into the steel slag, directly melting the modifiers by virtue of sensible heat of the steel slag, and changing the alkalinity of the steel slag by means of a molten state modifying method, wherein the adulterate amount of the modifiers is smaller than or equal to 25% by mass of the steel slag; and by adding the modifiers containing silicon oxide and / or iron oxide to recombine the component of the steel slag, increasing the contents of magnetite and hercynite so as to improve the recovery rate of the iron component. According to the method disclosed by the invention, sensible heat of the molten steel slag is effectively utilized, so that heat needs not to be compensated in the modifying process; the modifiers which are added into the steel slag are either cheap raw materials or solid wastes such as tailings and dust slime, so that optimization and synergic action of resources are realized. Meanwhile, by adding the modifiers containing silicon oxide and / or iron oxide and increasing the contents of magnetite and hercynite after component recombination, the recovery rate of the iron component in the steel slag is improved.
