Abstract:
The usage of rare earths in industries keeps increasing due to their key roles as alloying element. However, the supply is going to be limited, since the elements are produced locally with severe problem of contamination, which is also connected even to its recycling process generally done by chemical process.
In this talk, a pyro-recyling process will be introduced, in which the rare earth selectively is extracted by Mg, a typical low melting element. The product recycled is Nd-Fe-B, a typical composition of permanent magnet. Also, a concept of total recycling where each element input for recycling process connects to materialization will be introduced.
