These industries may include electronics, where REOs contribute to the fabrication of devices like smartphones, computers, high strength magnets, batteries, and advanced optics. The REO processed at the Bayan Obo mine is used in manufacturing processes where monazite and bastnasite are key materials for refining rare earth elements. 该数据集描述了稀土氧化物（REO）生产的过程链，目的是获取用于各种高科技行业的各种REO。这些行业可能包括电子行业，在那里REO有助于制造智能手机、计算机、高强度磁铁、电池和先进光学设备等设备。在白云鄂博矿加工的REO用于制造过程，其中独居石和氟碳铈矿是提炼稀土元素的关键材料。 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 data set describes the process chain of Rare Earth Oxide (REO) production for the purpose of obtaining various REOs utilized in a wide range of high-tech industries.

When utilizing this data for Life Cycle Assessment (LCA), take care to apply the preferred allocation method based on market-value for partitioning the environmental impacts among the different types of REOs, as per the metals industry's customary practices. The results reported should be carefully considered in light of Chinese-specific life cycle data when available to give a more accurate representation of the impacts. In absence of local data, refer to European life cycle inventory (LCI) databases. The lifecycle scope is cradle-to-gate with the functional unit set as 1 kg of REO. The results for both market and exergetic-based allocation are available and should be consulted according to the specific context of the assessment. 在使用此数据进行生命周期评估（LCA）时，请注意按照金属行业的惯常做法，采用市场价值为基础的配置方法，对不同类型的REOs的环境影响进行划分。报告的结果应在可用时仔细考虑中国特定的生命周期数据，以更准确地表征影响。在缺乏本地数据的情况下，请参考欧洲生命周期清单（LCI）数据库。生命周期范围是摇篮到大门，功能单位设定为1千克REO。市场和基于出热的分配的结果都是可用的，应根据评估的具体情况进行咨询。 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 2024-04-20T15:07:19.622445+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=ee4c231b-175b-4f02-8633-0ef4501b1413&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 heat Input 43.35 43.35 Coal Coal oxalic acid Input 19.89 19.89 Calculated Coke Coke oxalic acid Input 1.235 1.235 Calculated H2SO4 H2SO4 oxalic acid Input 43.35 43.35 Calculated NaOH NaOH Rare Earth Oxides Output 1.0 1.0 Calculated
