PROBLEM TO BE SOLVED: To provide a production method of a sinter ore in which, a large amount of fine ore which is generated in a large amount when performing development drilling and beneficiation on a mine, is blended, then mixed and granulated, and then is burned for agglomeration, especially capable of enhancing intensity of a pseudo particles after granulation, improving air permeability during burning, therefore improving productivity of a sinter ore, and producing a sinter ore excellent in quality such as reduction degradation resistance during use in a blast furnace.SOLUTION: Components excluding solid fuel, is blended so as to be 10% or more in mass ratio to a blended raw material, among fine particles having particle diameter of 20 μm or less which are separated when sieving is performed in water containing a sinter blend material such as an iron ore, therefore intensity of a pseudo particle acquired in granulation is improved and productivity and yield during sinter, are improved. |
