摘要： 1. A process for the recovery of a metallic nickel product in a solvent extraction process including the steps of:(a) forming a nickel ammine complex by stripping nickel from a nickel loaded organic phase with a high strength ammonia solution; and(b) reducing the nickel ammine complex with hydrogen from the high strength ammonia solution to produce a metallic nickel product.
