This thesis deals with Rare Earth Elements (REE), especially with
neodymium used in permanent magnets, from a very scientific basis
by providing basic research data. Despite the fact that REE are
newsworthy and very important elements for a considerable bandwidth
of todays' technologies, accompanied by the monopolistic
supply-situation and Chinese politics, there are inexplicable data
discrepancies about REE which have been recognized frequently but
usually have not been addressed accordingly. So this analysis
started with the hypothesis that the four application areas, namely
computer hard disk drives (HDD), mobile phones, wind turbines and
e-mobility (automotive traction), account for about 80% of the
global annual neodymium-demand. The research methodology was a
laboratory analysis of the composition of used magnets for HDDs and
mobile phones and a literature and official report analysis of wind
turbine and automotive neodymium use. The result was amazing and
the hypothesis had to be withdrawn as these four areas only account
for about 20% of neodymium use. This result raises some questions
concerning actual use and thus potential recycling options.
