摘　　要：针对镍铂二次资源回收工艺中的原料成分,探讨了镍铂合金靶材废料的湿法冶金分离回收技术,以及合金废料的氧化浸出处理及离子交换镍铂分离回收技术。通过单因素实验,确定了最佳工艺条件及工艺流程,实现了镍、铂的有效分离,分离提纯后得到符合国标质量要求的海绵铂和镍化合物晶体产品,铂回收率达99%,镍回收率97%。Aimed at nickel and platinum secondary resource, this paper studied the hydrometallurgy separation and recovery technology for spent platinum and nickel alloy targets, including oxidizing leaching and ion exchange.Through the single factor experiment, optimum technological conditions and process were determined, platinum and nickel were separated effectively. Through separation and purification, sponge platinum and nickel compounds crystal meeting national standard quality requirements were obtained, platinum and nickel recovery rate reached 99% and 97% resnectiwlv.
