[PDF] RARE EARTH ELEMENTS | Semantic Scholar

Geology. The rare earth elements (REEs), which include the 15 lanthanide elements (Z = 57 through 71) and yttrium (Z = 39), are so called because most of them were originally isolated in the 18th and 19th centuries as oxides from rare minerals. Because of their reactivity, the REEs were found to be difficult to refine to pure metal.
