Abstract The amount of a carbon iron composite used is appropriately adjusted when the carbon iron composite is used in a blast furnace, whereby a stable operation is provided. Ore and coke including the carbon iron composite and conventional coke are charged into the blast furnace. The percentage of the carbon iron composite used is 2% to 50% by mass of the coke. The percentage of the carbon iron composite used is preferably 25% by mass or more. The carbon iron composite preferably has a particle size of 15 mm to 40 mm. The carbon iron composite preferably has an iron content of 10% to 40% by mass.
