SELECTIVE PRECIPITATION OF METAL SULFIDES. |
摘要 |
<p>A method for recovering zinc ions by selective sulfide precipitation from an aqueous solution comprising zinc ions and metal ions of a metal that precipitates as metal sulfide at a pH lower than a pH at which zinc ions precipitate as zinc sulfide, the method comprising contacting the aqueous solution with a source of sulfide to precipitate the metal ions as the metal sulfide while avoiding the precipitation of the zinc sulfide thereby yielding the metal sulfide precipitate and a solution comprising zinc ions, and contacting the solution comprising zinc ions with a source of sulfide ion in a concentration sufficient to precipitate the zinc ions as the zinc sulfide.</p> |
