Samarium
Samarium is named from the mineral samarskite and was discovered in 1879. Samarium is found along with the other rare-earth minerals principally in monazite and bastnasite. The metal is isolated using ion exchange and solvent extraction methods. Samarium has a bright silver luster. Samarium is a small component of misch metal and along with other rare-earths is used for carbon lighting by the motion picture industry.
