The alkaline earth metals were precipitated either as sulfates or oxalates, leaving the alkali metal in the solution. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Earths are metallic oxides, and the corresponding metals were classified into the corresponding groups: rare earth metals and alkaline earth metals.
