Zusammenfassung:PURPOSE:To accelerate pseudo-granulation in starting materials to be sintered while adding slaked lime or quick lime by preparing a slurry contg. a specified amount of fine iron ore or mill scale having stuck hydrophobic oil and using the slurry as water for regulating water content. CONSTITUTION:Hydrophobic oil 2 is stuck to dried fine iron ore or mill scale 3 to obtain fine iron ore or mill scale 1 having stuck hydrophobic oil. The oil 2 is required only to be hydrophobic, and any of animal oil and vegetable oil is used. The fine iron ore or mill scale 3 is used in the form of fine powder having
