Description

The neodymium iron boron (NdFeB) magnet produced through this industrial process is intended for use in applications requiring high-strength permanent magnets. These magnets are commonly utilized in various technological devices such as hard disk drives, wind turbines, electric vehicles, and speakers due to their superior magnetic properties. When using the data set for the rare earth production process of neodymium and praseodymium for NdFeB magnets, please note that the allocation method is based on market prices of rare earth oxides (REOs). For users concerned with methodological consistency, consider the sensitivity analysis using mass-based allocation to estimate the impact of the allocation method on uncertainty. Ensure proper interpretation by considering this allocation method and the specific final solvent extraction step (SX5) where Nd and Pr are separated. The data is defined per functional unit of 1 kg of NdFeB magnet.

Technology

The basic process for Nd and Pr production is the same at all three deposits. It is identical for Nd and Pr except for the last solvent extraction step (SX5) where both are separated.
