Each subsection discusses one process of the LCA. Section 3.1 describes the conventional method of rare earths in China from mineral sources. Section 3.2 describes the production process used to transform neodymium oxide into an NdFeB magnet. Finally, section 3.3 describes two alternative recycling processes that could be used. Detailed information on the LCI, assumptions, and allocation choices can be found in the Supporting Information. None 无 None 无 None 无 None 无 Sprecher, B. et al.

When using the dataset related to the mining of REE containing ore, ensure that your life cycle assessment considers the specific environmental impacts associated with surface mining techniques, such as drilling and blasting. Account for the high ore grade of 4.1% REO in resource depletion calculations, and apply the dataset consistently for products that require rare earth elements. Pay attention to technological shifts that might alter the process efficiency or environmental impact. Review the detailed LCI, assumptions, and allocation choices in the supporting information of the data set to ensure data quality and representativeness. 在使用含稀土矿石开采相关数据集时，确保您的生命周期评估考虑了与露天采矿技术（如钻孔和爆破）相关的特定环境影响。在资源耗尽计算中计入高矿石品位4.1% REO，并且对需要稀土元素的产品一致地应用数据集。关注可能改变过程效率或环境影响的技术转变。复查数据集支持信息中详细的LCI、假设和分摊选择，以确保数据质量和代表性。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Tao Wang, twang@iue.ac.cn 汪涛, twang@iue.ac.cn twang@iue.ac.cn twang@iue.ac.cn 2023-12-24T16:06:40+08:00 2024-04-20T15:07:22.067781+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=7b497c8c-e1cb-4f8d-9862-a348b761be84&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses Electricity Input 16.2 16.2 Calculated Iron ore Input 1.7e-06 1.7e-06 Calculated recultivation, iron mine recultivation, iron mine blasting Input 0.0005 0.0005 blasting blasting Diesel oil,diesel oil Input 1.25 1.25 Rare Earth Oxides Output 1.0 1.0 LANGUAGE REO water Output 0.0034 0.0034 unspecified Output 0.00012 0.00012 iron Output 0.3 0.3 cerium Output 0.0164 0.0164 lanthanum Output 0.00984 0.00984 neodymium Output 0.00541 0.00541 praseodymium Output 0.00172 0.00172 europium Output 8.14e-05 8.14e-05 samarium Output 0.00041 0.00041 gadolinium Output 0.000206 0.000206 waste heat Output 0.00513 0.00513 radium-226 Output 0.01 0.01 thorium-232 Output 0.0506 0.0506
