Hydrometallurgy in the recycling of spent NdFeB permanent magnets
Kapitel i bok, 2018

Neodymium-iron-boron (NdFeB) magnets are used in many applications, from small consumer electronics to future sustainable technologies, e.g., electric transportation and wind power. Rare earth elements (REEs) amount to about a third of the composition of NdFeB magnets. Given that REEs are presently considered critical and have very high supply risk, their recycling from end-of-life products has received increased attention. Magnet-containing streams are valuable secondary sources of REEs, e.g., neodymium, praseodymium, dysprosium, and terbium.
