To provide a method for producing a sintered ore, which can enhance productivity by effectively using a returned ore in a dry state.
(1) In a method of producing sintered ore by using a mixture of grains granulated from a raw material to be sintered and all or some of the return ore which is an additive, as a raw material to be sintered and blended, the method for producing the sintered ore includes setting a ratio of the return ore to be added after the granulation of the raw material to be sintered, at 5 to 25 mass% with respect to the raw material to be sintered and blended. (2) The method decreases a water content in the raw material to be sintered and blended which has been added with the return ore by a range of 0.3 to 1.5 mass% compared to a water content of the granulated raw material to be sintered to which the return ore is not added, by adding the return ore. In the methods (1) or (2) for producing the sintered ore, it is preferable to selectively use a coarse grain portion in the return ore which has been classified into the coarse grain portion and a fine grain portion, as the return ore to be added after the granulation.
