| titleOfInvention | Method for removing chloride ions from nickel sulfate solution |
| abstract | The invention discloses a method for removing chloride ions from a nickel sulfate solution, which belongs to the technical field of hydrometallurgy and comprises the following specific steps: uniformly stirring a nickel sulfate solution containing chloride ions and sulfuric acid with the concentration of 93% to serve as a water phase, adding trioctyl tertiary amine into the sulfonated kerosene, and preparing an organic phase with the concentration of the trioctyl tertiary amine of 15% -25%; and (3) performing mixed extraction on the water phase and the organic phase, performing multi-stage countercurrent extraction, wherein the discharge outlet liquid of the water phase is relatively pure nickel sulfate liquid, the concentration of chloride ions is below 0.05g/L, and the organic phase is regenerated by water washing and recycled. The process has the advantages of low raw material cost, simple process, high labor production efficiency, clean production process, no pollution and the like. |
