PROBLEM TO BE SOLVED: To inexpensively produce a sintered ore of high quality at a high production rate and in a high yield. SOLUTION: This method for producing the sintered ore includes blending raw iron ores which are composed of iron ore (A) containing 9.0 mass% or more crystallization water, iron ore (B) containing less than 4.0 mass% crystallization water and iron ore (C) containing 4.0 to 9.0 mass% crystallization water. The raw materials (though the iron ores A, B and C are controlled so as not to contain 0.10 mass% or more P) are blended, by a ratio, in a range surrounded by a point (a), a point (b), a point (c), a point (d) and a point (e), shown in Fig.1, or preferably in a range surrounded by the point (b), the point (c), the point (d), the point (e), a point (f) and a point (g), shown in Fig.2. Then, the blend is sintered. COPYRIGHT: (C)2007,JPO&INPIT
