According to the present invention, by adjusting a mixing ratio [(C/F) × 100] between the mass of an iron ore raw material (F) having particles with a diameter of not more than 0.5 mm, and the mass of coke breeze (C) having particles with a diameter of not more than 0.5 mm, to a range of seven to eight percent, a precursor powder for sintering, which is excellent for efficiently producing sinter, can be adjusted, without depending on the quality of the iron ore. |
