Use advice for data set Users of this data set should apply the allocation method based on market prices of Rare Earth Oxides (REOs) as considered in this study, specifically for the production of 1 kg of NdFeB magnets. When modeling the life cycle assessment, attention should be paid to the methodological advice concerning the inclusion of recycling scenarios or exclusion criteria for materials. It is essential to utilize mass-based allocation as a sensitivity analysis to estimate uncertainties related to the allocation method. The technological applicability mentioned should be carefully adhered to when this data is used in environmental impact analyses or comparisons.

Data set use approval

General comment This data set represents the industrial process involved in the production of neodymium iron boron (NdFeB) magnets, which are critical components in various high-tech and clean energy applications such as in wind turbines, electric vehicle motors, and hard disk drives. It encompasses the rare earth crushing, in-situ leaching, and subsequent separation processes specific to the Bayan Obo region in China, where the basic production techniques for neodymium (Nd) and praseodymium (Pr) are identical until the solvent extraction step where they are separated.
