Title:
METHOD FOR MANUFACTURING ORE SLURRY, AND, METAL SMELTING METHOD
Document Type and Number:
Japanese Patent JP2023172493
Kind Code:
A
Abstract:
To provide a method for suppressing excessive viscosity increase of a slurry, which causes poor transfer, at a cost lower than conventional means, in production of the ore slurry for obtaining the ore slurry from raw material ore.SOLUTION: A method for producing an ore slurry comprises: a particle size distribution measurement step S11 in which particle size distribution is measured for each raw material ore group for raw material ores that have been grouped into a plurality of groups in advance; a mixing ratio determining step S12 for determining a mixing ratio of the raw materials ores for each raw material ore group; a blending step S13 for blending the raw material ores on the basis of the mixing ratio; a classification step 14 for obtaining a coarse ore slurry made of ore particles of under size by removing oversized ore particles; and an ore slurry concentration step S15 in which water contained in the crude ore slurry is separated and removed to concentrate ore components, and in the mixing ratio determination step S12, the mixing ratio is determined such that an average particle size after blending becomes a predetermined value or more.SELECTED DRAWING: Figure 2
