The other categories assessed in the literature review were mineral type, radioactivity, waste treatment, and co-mining. For mineral type, it was noted that the mineralogy accounted for in each study was different, which makes comparison difficult. For radioactivity, we marked with an X those studies which exemplified radioactivity flows in the LCI (if provided). For waste, we distinguished those LCIs which quantified waste treatment flows. For co-mining, since all REE are co-products of each other, this column is meant to highlight the co-products in addition to REE. None 无 None 无 None 无 None 无 Bailey, G. et al.

Bailey, G. et al. Review and new life cycle assessment for rare earth production from bastnäsite, ion adsorption clays and lateritic monazite. Resources, Conservation and Recycling 155, 104675 (2020). When using this dataset for Life Cycle Assessment, ensure you account for variations in mineralogy and processing routes, as they can affect the environmental impacts of REE production. Studies pertaining to radioactivity should include radioactivity flows if available. Quantification of waste treatment flows in LCIs is essential due to the potential environmental impacts. Co-mining aspects have to be considered, highlighting the co-products obtained in addition to REE. The functional unit for comparison is the production of 1 kg of a basket of REO (Rare Earth Oxides) from the specified mineralogical and processing route. 在使用此数据集进行生命周期评估时，确保计入矿物学和加工路线的变化，因为它们可能影响稀土生产的环境影响。涉及放射性的研究应包括可用时的放射性流量。由于潜在的环境影响，量化LCI中的废物处理流程至关重要。必须考虑共采矿的方面，突出除REE外获得的共产品。比较的功能单元是从特定矿物学和加工路线生产 1 公斤的REO（稀土氧化物）篮子。 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 2024-04-20T15:07:24.858137+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=92fea6a9-4fd7-4fdd-b4ee-9f76dd26172f&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 Sodium carbonate Input 1.0 1.0 Calculated Soda ash Soda ash transport in t*km,transport in t*km Input 0.53 0.53 Calculated transport in t*km,transport in t*km Input 9.54 9.54 Calculated Hydrochloric acid Input 1.0 1.0 Calculated Hydrochloric acid Hydrochloric acid Rare Earth chloride solution Input 1.77 1.77 Calculated RE Chloride RE Chloride Rare Earth chloride solution Output 1.0 1.0 Calculated RE Chloride RE Chloride water Output 0.00756 0.00756 Calculated Water Output 7.56 7.56 Calculated
