Title: THICKENER DEVICE FOR ORE SLURRY MANUFACTURING STEP, AND METHOD OF CONTROLLING SOLID COMPONENT RATIO FOR SAME
Abstract:
This invention comprises obtaining an ore slurry (A1) having a first solid component ratio lower than the target predetermined solid component ratio by thickening a first raw material ore slurry (A0), obtained by blending multiple types of ores, in a first thickener (10A); obtaining an ore slurry (B1) having a second solid component ratio higher than the target predetermined solid component ratio by thickening a second raw material ore slurry (B0), obtained by blending multiple types of ores, in a second thickener (10B); controlling the mixing proportion of the ore slurry (A1) having the first solid component ratio and the ore slurry (B2) having the second solid component ratio at a mixing proportion with which an ore slurry (C) with the target predetermined solid component ratio can be obtained, on the basis of the first solid component ratio and the second solid component ratio; and mixing the ore slurry (A1) having the first solid component ratio and the ore slurry (B1) having the second solid component ratio.
