镧系元素,是一种稀土元素,主要被用于制造计算机、手机和其他一些配件工具的磁体部分。到目前为止,中国是生产此类磁体材料的主要国家。因此,其市场价格也在很大程度上由中国决定。一直以来,美国都在积极寻找能够获取镧系元素更便宜的渠道。近日,美国能源部称开发出一个新项目——新型膜溶剂萃取系统,可以将镧族稀土元素从废弃电子产品中一次性重新提炼出来。美国能源部稀有材料研究所表明,他们开发出的这项新的技术能够从磁体废弃物中回收稀土元素。
Lanthanides, a rare earth element, are mainly used in the magnet part of computers, cell phones and other gadgets. So far, China is the main country producing such magnet materials. Therefore, its market price is also largely determined by China. All along, the United States is actively looking for cheaper access to lanthanides. Recently, the United States Department of Energy said it has developed a new project - a new membrane solvent extraction system, which can re-extract the lanthanide rare earth elements from waste electronic products once. The US Department of Energy’s Institute of Rare Materials has shown that the new technology they developed can recover rare earth elements from magnet waste.
