Abstract

Rare earth elements (REEs) are used in many applications such as in wind turbines, batteries, as catalysts, strong magnets, and in electric cars. The availability of rare earths is in partial decline. The price of REEs has escalated due to their high demand surpassing the supply. As we have only a few exploitable natural resources for mining rare earths around the world, we will have to rely on recycling the REEs from pre- and postconsumer scraps, mainly from the end-of-life products.
