Lanthanum is considered a rare earth metal because the process to mine it is difficult, time-consuming and expensive. Lanthanum is rarely the dominant lanthanide found in the rare earth minerals, and in their chemical formulae it is usually preceded by cerium. Rare examples of La-dominant minerals are monazite-(La) and lanthanite-(La).
Lanthanum, which is the first element of lanthanide series, is a silvery white metal and rare-earth element. Lanthanum can be mainly found in monazite and bastnasite. Although the source of lanthanum is not rare, but the process to get pure material is very complex.
