Isolation Here is a brief summary of the isolation of samarium.
Samarium metal is available commercially so it is not normally necessary to make it in the laboratory, which is just as well as it is difficult to separate it from as the pure metal. This is largely because of the way it is found in nature. The lanthanoids are found in nature in a number of minerals. The most important are xenotime, monazite, and bastnaesite. F. Lanthanoidswith even atomic numbers are more common.
