摘要
研究从钐钴和钕铁硼永磁废料中提取钴和钕的方法 ,比较不同的提取方法对杂质含量和提取率的影响 ,提出简单可行、效益良好的工艺条件 ,钴和钕的回收率均达 90
The methods of extracting rare materials from RECo_5 and Nd_2Fe_ 14B permanent magnetic waste materials have been studied to retrieve Cobalt and rare earth. Different methods are compared in terms of impurity content and extractive efficiency, and simple, feasible and beneficial conditions have been advanced in this paper by which the extraction yield of Cobalt and Neodymium achieves 90%.
