摘要
中国每年都会产生不同种类的稀土废料,这些废料中包含大量的稀土、铁、铝等有价金属,对稀土废料进行综合回收利用是解决中国稀土资源短缺的有效途径。对废旧稀土荧光粉、钕铁硼废料、稀土熔盐电解渣以及其他稀土废料的综合回收处理方法进行了综述,分析了它们的优势与共性,以期在实际处理过程中提供技术支持和帮助。
Different kinds of rare earth waste are produced each year in china. These wastes contain a large amount of rare earth, iron, aluminum and other valuable metals. Comprehensive recycling of rare earth wastes is an effective way to solve the shortage of rare earth resources. The comprehensive recycling of waste rare earth phosphors, Nd-Fe-B scrap, rare earth molten salt electrolytic slag and other rare earth wastes are reviewed, and their advantages and commonalities are analyzed in order to provide technical support and assistance in the actual treatment process.
