<p>Provided is a method for producing a starting material for sintering, wherein it is possible to improve productivity compared to conventional methods by effectively using high-carbon dust during the process in which the surface of pseudo particles is being covered with a solid-fuel-based powder starting material. When forming a limestone-based powder starting material base layer by supplying a limestone-based powder starting material to the surface of pseudo particles obtained by granulating a material containing SiO2 and iron ore and when forming a solid-fuel-based powder starting material outermost layer by supplying a solid-fuel-based powder starting material on the limestone-based powder starting material base layer, a solid-fuel-based powder starting material containing 5 to 40 mass% of high-carbon dust is used as the solid-fuel-based powder starting material.</p> |
