NICKEL RECOVERY PROCESS AND COMPOSITIONS FOR USE THEREIN |
摘要 |
<p>A process for the recovery of nickel from a nickel containing orein which the ore, particularly a laterite ore, is initially leached with an aqueous acid solution, after which the nickel is precipitated as nickel hydroxide by adding a hydroxide to the aqueous acid leach solution containing the nickel, followed by a re-leaching of the nickel with an aqueous ammoniacal solution and recovery of the nickel by a solvent extraction of the nickel from the aqueous ammoniacal solution with an organic phase of a water insoluble oxime extractant comprising a ketoxime containing less than 10 % phenols dissolved in a water-immiscible hydrocarbon solvent and the nickel recovered by electrowinning the nickel from the aqueous acid stripping solution employed to strip the nickel from the organic phase.</p> |
