数据集使用建议 | 从这项研究中得到的生命周期清单(LCI)数据集特定于南方七省通过氟碳铈矿路线的稀土元素溶剂萃取。在比较这个LCI数据集与其他数据集时应格外小心,因为矿物学、放射性和废物处理过程的差异可能导致不一致性。特别注意那些示例放射性并量化废物处理流量的研究所使用的方法论。在考虑共采影响时,重要的是除了REE之外还要评估共产品。这个LCI数据代表了与指定矿物和加工路线生产1公斤REO篮子相关的环境输入和输出。 |
产品或过程的技术目的 | 所述工艺在采矿行业中用于通过氟碳铈矿路线生产稀土元素(REE)。这包括使用溶剂萃取技术在沉淀和煅烧等初步过程之后提炼开采的矿石。开采的产品主要用于各种高科技应用,包括电子产品、磁铁、可再生能源技术以及化学合成中的催化剂。 |

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. | ||||
