Abstract

Today neodymium plays a very important role as a main component of Nd-Fe-B magnets, which are indispensable for clean energy application. Therefore, the short information about neodymium and its production in the last years are presented. The article briefly gives also the short characteristics of Nd-Fe-B magnets, as well as their appliances and methods of obtaining. For these magnets, the amount of production was compared in 1987-2016, and the main producers in 2015 are indicated. Perspectives for the production of Nd-Fe-B magnets in the following years are shown including the declining resources of rare earth metals and the simultaneous increase of their demand and taking into account the dominant producer and monopoly of China. The review of available methods of recycling of Nd-Fe-B magnets is presented focusing on hydrometallurgical and pyrometallurgical methods.

Keywords: Neodymium, Nd-Fe-B magnets, methods of Nd-Fe-B magnets recycling
