A method of granulating a sintering material for iron manufacturing which contains a powdery iron ore, the method comprising a step which comprises diluting fine particles having an average particle diameter of 200 mum or smaller beforehand with a solvent or part of the sintering material, adding the resultant mixture to the remaining sintering material, and granulating this mixture, the step being at least one step selected from the group consisting of the following (1), (2), and (3). A step which comprises diluting the fine particles with water so as to result in a slurry having a viscosity of 0.005 to 10 Pa.s, adding the slurry to a sintering material, and granulating the mixture. A step which comprises granulating beforehand the fine particles together with 13 to 60 wt.%, on a dry basis, of a sintering material containing iron ore as an essential component, adding the granules to the remaining sintering material, and granulating the mixture. A step which comprises mixing beforehand the fine particles with 0.3 to 10 wt.% of the sintering material on a dry basis, adding the mixture to the remaining sintering material, and granulating the mixture.
