RECOVERING METAL VALUES FROM LEACH RESIDUE |
摘要 |
<p>There is also provided a method of treating a metalliferrous material. The method includes providing a metalliferrous material including nickel, cobalt, and iron. At least a fraction of the metalliferrous material is leached with an aqueous solution including dissolved sulphuric acid and dissolved sulphur dioxide in a reaction zone so as to effect production of a leachant including nickel sulphate, cobalt sulphate, and iron sulphate. The leachant is contacted with a reagent material in a reaction zone, wherein the reagent material is aqueous ammonia solution, so as to effect production of a reaction product including a product solution component and a solid residue component. The nickel and cobalt are concentrated in the product solution component, and the iron is concentration in the solid residue component.</p> |
