Elevated contents of rare earth elements (REE) in apatite from the apatite iron ores in Northern Sweden was early noticed and investigated in some detail in the 1960’s2. The samples then consisted of gangue minerals from different ores, flotation concentrates of apatite and handpicked apatite grains.
Rare earth mineral that form their own deposits: Bastnaesite, Monazite, Xenotime. To extract the rare earth elements industrial importance are the following minerals: S ynchysite, Euxenite, Gadolinite, Loparite; Rare earth elements are extracted from the following minerals too: Churchite, Rhabdophane, Parisite, Fergusonite, Samarskite, Allanite.
