Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for simply performing a dust-treatment at a low cost in a smelting reduction facility. SOLUTION: A smelting reduction method is provided with a process, in which the dust developed in iron-works and charged into a raw material dryer 10 to together with raw material for smelling reduction and dried, a process, in which the dried raw material and dust are classified into coarse grain and fine powder, a process, in which the classified coarse grain is charged into the smelting reduction furnace 40, and a process, in which the classified fine grain is blown into slag and molten iron portion in the smelting reduction facility 40.
