Document Type and Number:
WIPO Patent Application WO/2017/057856
Kind Code:
A1
Abstract:
The present invention relates to a method for separating and sorting limonite ore and saprolite ore from nickel laterite ores. A method for separating and sorting laterite ores, according to the present invention, separates gangue, which exceeds a first particle size, and intermediate products of the first particle size or less from each other through particle size separation for raw laterite ores, and then removes the moisture of the intermediate products. In addition, the intermediate products are crushed so as to have a second particle size or less, and then the crushed intermediate products are classified and separated into a first product and a second product. The separated coarse first product is classified as saprolite ore and used as a raw material for dry refining, and the second fine product is classified as limonite ore and used as a raw material for wet refining.
