Abstract

A method for recycling steelmaking dusts has a granulating step of mixing steelmaking dusts, containing as a principal component iron and oxides thereof produced during the steelmaking in a melting furnace, with a powder containing carbon as a principal component and granulating the resultant mixture to provide mixed granules, a water impregnating step of immersing the mixed granules in a water to allow them to be impregnated with the water, a solidifying step of molding the water impregnated, mixed granules under pressure within a mold assembly to provide a solid body of the steelmaking dusts, a step of transporting the solid body of the steelmaking dusts as a raw material to be charged into the melting furnace, an enhancing step of increasing the concentration of zinc in the dusts, and a dezincing step of dezincing the dusts during a period from acquisition of the steelmaking dusts out of the melting furnace to the solidifying step.
