. The total recoveries of rare earth, nickel and cobalt are 98.9%, 98.4% and 98.5%, respectively. Key words: solid waste materials; hydrogen-nickel battery; recovery; rare earth  ... powder and the steel band. And the foaming nickel and copper network anodes can be recovered directly. 3) In the recovery process of rare earth, the leaching solid-to-liquid ratio is controlled......
High-efficiency simultaneous extraction of rare earth elements and iron from NdFeB waste by oxalic acid leachingQingsheng Liu1,Tao Tu1,2,Hao Guo3,Huajin Cheng1,Xuezhong Wang11. Faculty of Materials...:Iron can not be recovered at high value because only rare earth elements are effectively recovered from NdFeB waste via oxidation roasting-hydrochloric acid......
