Use advice for data set Users applying this data set in a Life Cycle Assessment must consider the specific nature of the NdFeB magnet production process, with particular attention to the solvent extraction step which involves the separation of neodymium (Nd) and praseodymium (Pr). For impact assessment purposes, it is crucial to account for the allocation method based on market prices of rare earth oxides, and also to incorporate a sensitivity analysis via a mass-based allocation approach to estimate uncertainties pertinent to the allocation method. The function of the process data is to analyze the environmental impacts per 1 kg of NdFeB magnet produced.

Data set use approval

General comment This data set represents the production process for neodymium iron boron (NdFeB) magnets, which are critical components in various high-tech applications including electric motors in hybrid and electric vehicles, wind turbine generators, and hard disk drives. The process encompasses rare earth solvent extraction and precipitation, and in-situ leaching specifically within the Bayan Obo region in China. This data set is primarily valuable for stakeholders and industries involved in the production or utilization of NdFeB magnets. Nd and Pr are essential elements in this process, and despite their extraction and processing being similar, they are separated in the final solvent extraction step.
