Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for effectively utilizing iron-making dust as a resource with which the iron-making dust generated from the iron-making process of reducing, melting, refining, etc., are fully regeneration-utilized in the iron-making process, and zero-emission of the iron-making dust is realized and an infrastructure scale needed in a plurality of iron-works can be minimized. SOLUTION: In the method for effectively utilizing the iron-making dust as the resource generated in the iron-making process, such as the reducing, melting, refining, this method is characterized in that the iron-making dust containing ≥0.1% volatile metal, such as Zn, is used as a desiliconizing agent or dephosphorizing agent, and collected dust generated at the desiliconizing time or dephosphorizing time and excessive dust which can not be used as the desiliconizing agent and dephosphorizing agent, is kneaded together with a carbonaceous material for reduction to form an aggregate, and reduced iron obtained by reducing this aggregate with an exclusive-use reducing furnace, is used as a steelmaking raw material, and the collection dust generated in the exclusive-use reducing furnace, is used as a non-ferrous raw material.
