| titleOfInvention | Ore slurry pretreatment method, ore slurry manufacturing method |
| abstract | A wet smelting method for nickel oxide ore, which can effectively reduce the amount of acid used in the leaching process and the amount of neutralizing agent used in the final neutralization process without reducing the actual yield of nickel. The ore slurry pretreatment method of the present invention is a pretreatment method for ore slurry used for leaching in the wet smelting method of nickel oxide ore. At least one of a hydrocyclone and a density separator is used to separate the ore slurry into a coarse particle part and a fine particle part, and the fine particle part is supplied to the leaching treatment; in the second separation process, at least a spiral separator is used to separate the The coarse particles separated in the first separation process are separated into a heavy specific gravity part and a light specific gravity part, and the heavy specific gravity part is supplied to the leaching process; in the vibrating screen process, the light particles separated in the second separation process are separated by a vibrating screen. The specific gravity part is separated into an upper part of the screen and a lower part of the screen, and the ore slurry in the lower part of the screen is supplied to the leaching process. |
