In the whole production processes, we apply the mass-based allocation principle to our assessment by considering the scandium oxide as the main product, while Fe concentrate, REs concentrate, S concentrate, Fluorite coarse ore and Nb concentrate are considered as by-products, and the detail is shown in Supporting Information ( None 无 None 无 None 无 None 无 Wang, L., Wang, P., Chen, W.-Q., Wang, Q.-Q. & Lu, H.-S. Environmental impacts of scandium oxide production from rare earths tailings of Bayan Obo Mine. Journal of Cleaner Production 270, 122464 (2020).

Journal of Cleaner Production 270, 122464 (2020). When using this data set for Lifecycle Assessment (LCA) of scandium oxide, it is crucial to apply the mass-based allocation principle as per the methodological advice provided. This entails giving appropriate consideration to scandium oxide as the main product and adequately allocating environmental impacts among the by-products, which include Fe concentrate, REs concentrate, S concentrate, Fluorite coarse ore, and Nb concentrate. Ensure that all inputs and outputs are accounted for over the entire production process, from cradle to gate, for the production of 1 kg of scandium oxide. Always refer to the Supporting Information for detailed allocation processes. 在使用该数据集进行氧化钪的生命周期评估（LCA）时，必须按照提供的方法学建议应用基于质量的分摊原则。这包括适当地将氧化钪视为主产品，并在副产品之间适当分配环境影响，副产品包括铁精矿、稀土精矿、硫精矿、萤石粗矿和铌精矿。确保在整个生产过程中，从摇篮到大门，计算生产1公斤氧化钪的所有输入和输出。详细的分摊过程请始终参阅支持信息。 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 2024-04-19T20:24:18+08:00 2024-04-20T15:07:18.288767+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=1ae3e767-7646-4fc3-9763-93bb95c8a87b&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 tailings (unspecified) Input 64363.33 64363.33 Measured water Input 753955.18 753955.18 Measured Electricity Input 3138.408 3138.408 Measured process steam Input 60500.0 60500.0 Measured tributylphosphorotrithioate Input 6.5 6.5 Measured tributyl phosphate (TBP) tributyl phosphate (TBP) P0507 Input 5.33 5.33 Measured P507, 2-Ethylhexylphosphonic acid mono-2-ethylhexyl ester P507, 2－乙基己基膦酸单2－乙基己基酯 Kerosene Input 6.5 6.5 Measured Sodium silicate Input 650.01 650.01 Measured Water glass Water glass Polyglycerol fatty acid esters (PGFEs) Input 7.67 7.67 Measured Carrier (fatty ester of polyglycolether and modified polyalcohol) Carrier (fatty ester of polyglycolether and modified polyalcohol) Spray mold Input 5.33 5.33 Measured Activating reagent , Ammonium chloride (Salmiac, Solvay process) Activating reagent , Ammonium chloride (Salmiac, Solvay process) phenanthrene Input 388.02 388.02 Measured Collector, DE: Phthalic anhydride Collector, DE: Phthalic anhydride oxalic acid Input 50.17 50.17 Measured sulphuric acid Input 1767.83 1767.83 Measured Hydrochloric acid Input 77.06 77.06 Measured Hydrochloric acid Hydrochloric acid sodium hydroxide Input 77.06 77.06 Measured hydrogen peroxide Input 21.5 21.5 Measured arsenic trioxide Output 1.0 1.0 Measured Concentrate Output 11068.33 11068.33 Measured Fe concentrate Fe concentrate Rare Earth concentrate Output 2455.0 2455.0 Measured RE concentrate RE concentrate Concentrate Output 1020.0 1020.0 Measured S concentrate S concentrate Concentrate Output 32478.33 32478.33 Measured Fluorite coarse ore Fluorite coarse ore Concentrate Output 796.67 796.67 Measured Nb concentrate Nb concentrate Non-methane volatile organic compounds Output 0.69 0.69 Measured NMVOC NMVOC methane (fossil) Output 3.14 3.14 Measured 原文未区分bio和fossil，根据专家判断此处为fossil ammonia Output 0.26 0.26 Measured particles (PM2.5 - PM10) Output 0.44 0.44 Measured Radioactive dust, waste Output 0.000651 0.000651 Measured RS (Th, U) , Radioactive dust, waste RS (Th, U) , Radioactive dust, waste sulfur dioxide Output 7.38 7.38 Measured Nitrogen oxides Output 5.24 5.24 Measured Nitrogen oxide Nitrogen oxide carbon monoxide,carbon monoxide (fossil) Output 3.32 3.32 Measured 原文未区分bio和fossil，根据专家判断此处为fossil carbon dioxide (fossil) Output 853.11 853.11 Measured 原文未区分bio和fossil，根据专家判断此处为fossil water Output 678106.66 678106.66 Measured waste water - untreated Output 3226.23 3226.23 Measured Oils, unspecified Output 0.01 0.01 Measured Sulfidic tailing Output 10546.67 10546.67 Measured Sc tailings Sc tailings Waste (solid) Output 6502.66 6502.66 Measured
