Claim Text:
1. A method for producing an ore slurry from raw material ores comprising: a pulverizing/classifying step of pulverizing the raw material ores and classifying the resulting ores at a predetermined classifying point so that oversized ore particles are removed so as to obtain a coarse ore slurry composed of undersized ore particles; a grain size measuring step of measuring the grain size of the coarse ore slurry obtained by the pulverizing/classifying step; and an ore slurry condensing step of loading the coarse ore slurry to a solid-liquid separation device and separating and removing moisture contained in the coarse ore slurry therefrom so as to condense ore components, wherein in the case when the grain size measured in the grain size measuring step is lower than a predetermined value, one portion of the oversized ore particles that have been removed in the pulverizing/classifying step is loaded and added to the solid-liquid separation device in the ore slurry condensing step.
