Document Type and Number:
WIPO Patent Application WO/2024/038643
Kind Code:
A1
Abstract:
The present invention proposes a method for producing a sintered ore with high productivity without requiring both an expensive anionic polymer dispersant and a step for grinding an iron ore into a fine powder. The present invention provides a method for producing a sintered ore, wherein a blended sintering starting material including iron ores of a plurality of brands is granulated together with additive water in a granulator, and the resultant granulated starting material for sintering is fired in a sintering machine so as to obtain a sintered ore. With respect to this method for producing a sintered ore, some or all of the additive water during the granulation is replaced with a dust slurry solution that is obtained by suspending solid dust in water at a concentration of 20-55 mass%.
