Use advice for data set
When using this data in Life Cycle Assessment (LCA), it is important to consider the allocation method based on the mass of produced Rare Earth Elements (REEs) along with their market prices. Environmental impacts should be compared for the production of 1 kg Dysprosium across different sources, including IAC (Southern China), B/M ore (Bayan Obo), and eudialyte (Norra Kärr). Due to varying compositions of the ores, the allocation factor must be assessed individually for each site. It is also necessary to account for site-specific technological applicability and processing efficiencies in the LCA model.

General comment
The technical use of the process involves the production of Dysprosium (Dy) through the precipitation of rare earth elements from a filtrate and subsequent leaching with hydrochloric acid (HCl). This process is specific to the extraction and refinement of dysprosium from REE containing ores in Southern China and Bayan Obo regions. Dysprosium is a rare earth element commonly used in permanent magnets, which are essential components of modern electronics, electric vehicles, and wind-turbine generators, among other high-tech applications.
