| 数据集使用建议 | 在使用概述的稀土元素（REE）选矿过程的LCA数据集时，从业者必须在将这些数据应用于他们的评估时考虑矿物学和加工路线的具体情况。特别注意包括从采矿到溶剂提取的完整生命周期，包括沉淀和煅烧过程。务必考虑不同矿物类型、放射性水平、废物处理程序以及除稀土元素外的共产品。为了比较目的，必须注意不同研究之间矿物学的差异，因为直接比较可能很有挑战性。数据应用的功能单元是生产1公斤混合REO篮子。确保任何涉及此数据的分析都准确符合这些方法论参数。 |
| 产品或过程的技术目的 | 该工业过程涉及使用氟碳铈矿路线的稀土元素（REE）选矿，该过程涉及含稀土元素矿石的处理。这个过程在生产对各种先进技术至关重要的含稀土材料中至关重要。这些材料通常用于制造高性能磁铁、催化剂、合金、玻璃添加剂，以及电子产品中，如智能手机和先进的防御系统。该工业过程特别关注的成果是生产1公斤篮子稀土氧化物（REO）。 |

| 与LCI方法方法/解释的偏差 | In this study, the REE production system was analyzed from mining up to and including solvent extraction which contains product finishing processes such as precipitation and calcination (Fig. 1). 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. | ||||
