    摘要： A method for recovering chromite from ore slurry obtained by processing nickel oxide ore, the raw material, in a plant for the wet smelting of nickel oxide ore. In the method 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. The method 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%.
