The environmental impacts of rare earth mining have recently caused public concern, because demand for the rare earth elements neodymium (Nd), praseodymium (pr), dysprosium (Dy), and terbium (Tb) is expected to increase strongly as a result of their use in magnets for electric cars and other emerging applications. Therefore, we analyzed the future environmental impacts of producing these rare earth metals per kilogram and for global production in the year 2035 to obtain insights into their relevance and draw conclusions about suitable mitigation measures. We introduced a new stepwise approach that combines future scenarios of metal demand, policy measures, mining sites, and environmental conditions with life cycle assessment data sets.

未来磁铁应用稀土供应对环境的影响

稀土开采对环境的影响最近引起了公众的关注，因为稀土元素钕 (Nd)、镨 (pr)、镝 (Dy) 和铽 (Tb) 的需求预计将强劲增长。用于电动汽车和其他新兴应用的磁铁。因此，我们分析了每公斤生产这些稀土金属和 2035 年全球生产的未来环境影响，以深入了解它们的相关性并得出有关适当缓解措施的结论。我们引入了一种新的逐步方法，将金属需求、政策措施、采矿地点和环境条件的未来情景与生命周期评估数据集相结合。
