Title:
METHOD FOR MANUFACTURING ORE SLURRY, AND HYDROMETALLURGICAL METHOD FOR NICKEL OXIDE ORE
Document Type and Number:
WIPO Patent Application WO/2022/138239
Kind Code:
A1
Abstract:
Provided is a method with which it is possible, when manufacturing an ore slurry containing a metal ore such as nickel oxide ore as a raw material, to obtain an ore slurry in which the solid content and the slurry density are raised without increasing, inter alia, the amount of flocculant used. The present invention is a method for manufacturing an ore slurry in which a slurry containing a metal ore is concentrated and an ore slurry to be provided to a reaction is manufactured, the method including using at least two thickeners, and thickening a prescribed proportion of the slurry, not including the entire amount, in two stages. The second-stage thickening performed on the prescribed proportion of the slurry that has been subjected to the first-stage thickening, and thickening performed on the remaining proportion of the slurry, are performed using the same thickener.
