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 The result was amazing and the hypothesis had to be withdrawn as these four areas only account for about 20% of neodymium use.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. 410 0$aSpringer theses. 606 $aRare earth metals 615 0$aRare earth metals. 676 $a338.27494 676 $a546.41 700 $aZepf$b Volker$01060383 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910437956103321 996 $aRare Earth Elements$92513073 997 $aUNINA
