As the ores have different compositions, the allocation factor has to be assessed individually for each site.None无None无None无None无Zapp, P., Marx, J., Schreiber, A., Friedrich, B. & Voßenkaul, D.

Comparison of dysprosium production from different resources by life cycle assessment. Resources, Conservation and Recycling 130, 248–259 (2018).Users of this LCA data should consider the allocation method used in the study when applying the data to their own assessments. The allocation, based on the mass of produced REEs combined with their market prices, should be carefully applied to ensure accurate environmental impact evaluations. Users should also pay attention to site-specific data such as ore composition, technological applicability, and region-specific ecological impacts. It is advised to reassess the allocation factor individually for each site to maintain the robustness of comparative analyses.使用此生命周期评估(LCA)数据的用户应考虑研究中使用的分配方法，当将数据应用到自己的评估中时。基于生产的稀土元素的质量与其市场价格的分配方法，应谨慎应用以确保准确的环境影响评价。用户还应注意特定场所的数据，如矿石成分、技术适用性和地区特定的生态影响。建议重新评估每个场点的分配因素，以保持比较分析的严谨性。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.cntwang@iue.ac.cntwang@iue.ac.cn2024-01-04T18:04:32+08:002024-04-20T15:07:16.869113+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=851932fb-b9aa-4af6-9eb3-ec016eb5419f&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usesElectricityInput16.27216.272CalculatedElectricity mix 2014Electricity mix 2014Sodium silicateInput0.7890.789Unknown derivationSodium silicate, spray powder, 80 %Sodium silicate, spray powder, 80 % Fatty acid Input0.3290.329Unknown derivationfatty acid, from vegetable oilfatty acid, from vegetable oilChemicals organic,Chemicals, organic Input0.2730.273Unknown derivationchemical, organic.
