HYDROMETALLURGICAL PROCESS FOR NICKEL OXIDE ORE |
摘要 |
Provided is a hydrometallurgy method that is for nickel oxide ore, increases the durability of the production equipment in the method for hydrometallurgy of a nickel oxide ore by means of a high-pressure acid leaching method, involves simplified production equipment, has suppressed environmental risk and costs resulting from a reduction in the volume of a tailing dam that stores waste material, and achieves the separation/recovery of recyclable impurity components. The hydrometallurgy method for nickel oxide ore and that recovers cobalt and nickel using a high-pressure acid leaching method is characterized by including: step (A) (step for separating/recovering chromite particles); and at least one step selected from step (B-1) (step for neutralizing leachate by means of Mg-based neutralizer) and step (B-2) (step for neutralizing leaching residue slurry by means of Mg-based neutralizer). |
