The rare earth content at Ilímaussaq (Kringlerne) in Greenland
The ore in the deposit is one of the largest deposits of heavy
rare earths in the world. Rare earths are among the critical
materials for the future and are needed for among other things
permanent magnets used in wind turbines, generators for electrical
and hybrid cars, and hard disc drives.
The ore was confirmed to contain 1.8 % zirconium oxide, 0.2 %
niobium oxide, 0.5 % light rare earths, and 0.15 % heavy rare
earths. Among the rare earths, dysprosium was especially
The ore was found to consist of a wide range of minerals
including K-containing feldspar, Fe-containing arfvedsonite and
rare earth, containing eudialyte.
All together the data for the ore made public by Tanbreez
previously was verified.
