These oxides are essential components in the manufacturing of advanced technology products such as smartphones, computer hard disks, wind turbines, hybrid and electric vehicles, and LED lights. 白云鄂博工艺提取的稀土氧化物（REO）主要用于包括电子、磁铁、光学以及作为汽车和石化行业催化剂等各种高科技领域。这些氧化物是制造智能手机、计算机硬盘、风力涡轮机、混合动力和电动车辆以及LED灯等先进技术产品的必要组分。 The scope of the LCA is cradle-to-gate and the functional unit was chosen as 1 kg of REO. 4 2014 Bayan Obo (China) The process chain for REO production includes mining followed by beneficiation, calcination, extraction, and roasting stages, see Figure 2. The first step in REO production is mining, wherein crude ore is blasted and transported for further refining. Crude ore abstracted from the Bayan Obo mine is composed of both monazite and bastnasite. REO 生产的工艺链包括采矿，然后是选矿、煅烧、提取和焙烧阶段，见图 2。REO 生产的第一步是采矿，其中原矿石被爆破并运输以进一步精炼。从白云鄂博矿开采的原矿石由独居石和氟碳铈矿组成。 The rare earth oxides (REOs) extracted through the Bayan Obo process are primarily used in various high-technology sectors, including electronics, magnets, optics, and as catalysts in automotive and petrochemical industries.

Users of this LCA data set should primarily apply the market-value-based allocation method recommended by the metals industry to partition environmental impacts among the different types of REOs produced. Additionally, specific attention should be given to the technological stages within the process chain, namely mining, beneficiation, calcination, extraction, and roasting. Users are advised to use Chinese-specific life cycle data when available to reflect regional environmental impact accurately. However, if not available, European life cycle inventory (LCI) data sets can be used as a substitute. When using the data set to evaluate the production of individual REEs or REE-based technologies and products, the conservative nature of the LCA results should be considered. 使用这一LCA数据集的用户应主要采用金属行业推荐的基于市场价值的分配方法来划分生产的不同REOs之间的环境影响。 此外，应特别注意工艺链内的技术阶段，即采矿、选矿、煅烧、提取和焙烧。 建议用户在中国特定的生命周期数据可用时使用，以精确地反映区域环境影响。 但是，如果没有可用的数据，可以使用欧洲生命周期清单（LCI）数据集作为替代。 当使用数据集评估单个REE或基于REE的技术和产品的生产时，应考虑LCA结果的保守性。 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 2024-04-19T19:30:05+08:00 2024-04-20T15:07:19.618174+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=ab24cf46-3bf8-456d-90c7-d5e40f41dc69&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 hydrogen chloride Input 1.366 1.366 Calculated Nd2O3 Nd2O3 hydrogen chloride Input 0.854 0.854 Calculated Light Light hydrogen chloride Input 1.604 1.604 Calculated Medium Medium hydrogen chloride Input 6.418 6.418 Calculated Heavy Heavy chloride Output 0.06 0.06 Calculated chloride chloride hydrogen chloride Output 0.03 0.03 Calculated hydrogen chloride hydrogen chloride
