REAP - Rare-Earth Extraction from Audio Products

基于钕铁硼(NdFeB)的稀土磁体是电动汽车的关键材料，用于驱动电机、发电机、动力转向和扬声器。近年来，稀土的供应受到了主要生产商中国的相当大的限制。回收稀土磁铁提供了一个重要的机会，REAP的目标是为扬声器市场开发回收供应链。REAP(从音响产品中提取稀土)将研究从汽车和消费音响模块中释放稀土磁铁的新方法。EMR将对汽车和平板电视扬声器废料进行预处理，向HyProMag有限公司提供含有NdFeB磁铁的废部件饲料。HyProMag将与伯明翰大学合作评估一项专利工艺，将磁铁提取为退磁合金粉末，可用于磁铁的再制造。将为来自不同来源的发言者确定废料的质量、数量、可获得性和价值，并对废料的附加值进行计算。Hypromag有限公司正在开发的短路循环回收工艺与磁体的初级生产相比，将具有显著的环境效益。

Rare earth magnets based upon neodymium iron boron (NdFeB) are a key material in electric vehicles where they are used in drive motors,generators, power steering and in loudspeakers. In recent years the supply of rare earths has come under considerable constraint from the main producer, China. Recycling of rare earth magnets presents a significant opportunity and REAP aims to develop a recycling supply chain for the loudspeaker market. REAP (Rare-Earth Extraction from Audio Products) will investigate novel ways of liberating rare earth magnets from automotive and consumer audio modules. EMR will pre-process automotive and flat screen TV loudspeaker scrap to provide a feed of scrap components containing NdFeB magnets to HyProMag Ltd. HyProMag will evaluate a patented process in conjunction with the University of Birmingham to extract the magnets as a demagnetised alloy powder, which can be used in the remanufacture of magnets. The quality, quantity, availability and value of the scrap will be determined for speakers from various sources and a calculation of value added to the scrap will be made. The short loop recycling processes which are being developed by Hypromag Ltd will have a significant environmental benefit compared to primary production of magnets.
