Method for recovering chromite, and method for wet smelting of nickel oxide ore |
摘要 |
Provided is a method for efficiently recovering chromite from ore slurry obtained by processing nickel oxide ore, which is the raw material, in a plant for the wet smelting of nickel oxide ore. The present invention is a method for recovering chromite in which chromite is separated and recovered from an ore slurry obtained from a nickel oxide ore when nickel and cobalt are recovered from the nickel oxide ore, wherein the method for recovering chromite has: a grain diameter separation step for separating the ore slurry on the basis of a predetermined classification point according to the difference in the grain diameter of particles contained in the supplied ore slurry; and a sedimentation separation step for causing the oversized ore slurry separated in the grain diameter separation step to undergo sedimentation and concentration on the basis of a target classification point, and recovering the chromite. The coarse particle content of the oversized ore slurry separated in the grain diameter separation step is adjusted to 30-50%. |
