Other minerals that have been used as a source of rare earths are apatite, euxenite, gadolinite, and xenotime. |
It is found with other rare earth elements in minerals such as monazite, cerite, gadolinite, xenotime, and euxenite. |
In his 1885 report, Eakins described allanite and gadolinite from the area. |
The rare earth metals are found in the minerals gadolinite, samarskite, fergusonite, euxenite and cerite. |
In 1797 Ekeberg showed that gadolinite contained another rare earth, which was given the name yttria. |
Yttria may be obtained from gadolinite by a similar process to that by which glucina is extracted from the beryl. |
