APPARATUS FOR PRODUCING ORE SLURRY AND PROCESS FOR PRODUCING ORE SLURRY

摘要

An apparatus for producing an ore slurry and a process for producing an ore slurry are provided with which it is possible to produce an ore slurry having a high solid content and a high specific gravity, while maintaining a slurry throughput. The apparatus A for producing an ore slurry is equipped with: a first thickener 1 in which a feed ore slurry is preliminarily concentrated to obtain an intermediate ore slurry; and a second thickener 2 in which the intermediate ore slurry is concentrated to obtain a concentrated ore slurry and which has a higher thickening effect than the first thickener 1. Since the intermediate ore slurry obtained by preliminary concentration in the first thickener 1 is fed to the second thickener 2, the ore slurry in the second thickener 2 shows an increased sedimentation rate and the slurry throughput can be increased. Furthermore, since the latter stage is the second thickener 2, which has a high thickening effect, a concentrated ore slurry having a high solid content and a high specific gravity can be produced.
