Description

The bastnaesite route from the Seven Southern Provinces for mining and in situ leaching is used in the production of rare earth elements (REEs). This specific process is a part of the overall REE production system being studied and is crucial for the extraction of REEs, which are vital in the manufacture of high-tech devices, magnets, alloys, and various industrial and consumer products. When utilizing the LCA data set for REE production via the bastnaesite route, users should account for variations in mineralogy, radioactivity levels, waste treatment practices, and co-product yields as these factors may significantly influence environmental impact assessments. It may also be important to note differences in methodological approaches for comparability. The given functional unit is the production of 1 kg of the basket REO; users must ensure that this unit aligns with their study's scope and matches the intended usage to avoid discrepancies in the assessment results. Pay special attention to the inclusion or exclusion of radioactivity flows and waste treatment flows in the Life Cycle Inventory (LCI). For co-products, assess the relevance and included quantities within the scope of your study.

Technology

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
