PROBLEM TO BE SOLVED: To provide a method for pretreating raw materials for sintering by which, when manufacturing sintered ore using a thermally decomposable auxiliary raw material for sintering which is decomposed by heat to generate gas, the inhibition of air permeability in a sintering machine can be prevented and the sintering properties of the resultant sintered ore can be improved. SOLUTION: The raw materials for sintering can be obtained by mixing the thermally decomposable auxiliary raw material for sintering 10 which is decomposed by heat to generate gas with iron ore fines 11 and other raw materials for sintering. In the above process, the auxiliary raw material 10 and the iron ore fines 11 are pelletized in a pan pelletizer to prepare a pellet 20 in which the iron ore fines 11 are allowed to adhere to the periphery of the auxiliary raw material 10 to be nuclei, and this pellet 20 is mixed with the other raw materials for sintering.
