PROBLEM TO BE SOLVED: To provide a producing method of low slag sintered ore having 6-9% CaO concn. and securing the bonding among ores by forming molten auxiliary raw material. SOLUTION: The bonding among the ores in sintering reaction is more fastened, as the fluidity of the molten material is higher. As a component improving the fluidity of the molten material, MgO is recomended and as the MgO source in the raw material, dolomite is the most suitable raw material. Further, conditions for displaying the improving effect of the fluidity of molten material by using the dolomite is as follows. The dolomite containing >=18 wt.% MgO concn. is used. Blending ratio of the dolomite is desirable to be∞2.5%. Grain size of the dolomite is desirable to be >=60 wt.% grain having <=1 mm grain diameter.
