钕铁硼废料资源化回收利用研究进展

Research progress on the recycling and utilization of Nd-Fe-B wastes

中国每年会产生很多钕铁硼废料,这些废料中含有大量的稀土等有价元素。对钕铁硼废料进行资源化回收利用有助于改善中国稀土资源短缺、环境污染和资源浪费的问题。钕铁硼废料的绿色回收前景广阔,因此有必要对钕铁硼废料的资源化回收利用做更加全面和系统的研究。文中对一些传统钕铁硼废料回收工艺和钕铁硼废料回收的新方法进行了综述,并总结了这些方法的特点,以期在高效回收钕铁硼废料工艺的研究上提供指导和帮助。

A lot of N-Fe-B wastes,which contain a large number of valuable elements such as rare earth,are produced in China each year.Recycling them helps a lot when it comes to coping with the rare earth resource shortage,environmental pollution and resources waste in China.The green recycling of them presents a promising prospect.Therefore it is of great necessity to do a more comprehensive and systematic study on it.In order to provide guidance and help for the research of efficient recycling of Nd-Fe-B wastes process,both traditional and new recycling methods are reviewed and the characteristics of the new methods are summarized as well in this paper.
