Lanthanum (La) - CONCENTRATION OF MINERALS

2021-7-29 · Lanthanum (La) is contained in the following rare earth mineral:. Bastnaesite; Davidite; Monazite; L amprophyllite; C hevkinite; Rhabdophane; Area of application: This silver-white metal is one of the most reactive rare earth elements. It is used to make special optical glasses, including infrared absorbing glass, camera and telescope lenses, and can also be used to make steel more malleable.

Lanthanum - Element information, properties and uses ...

Lanthanum is found in ‘rare earth’ minerals, principally monazite (25% lanthanum) and bastnaesite (38% lanthanum). Ion-exchange and solvent extraction techniques are used to isolate the ‘rare earth’ elements from the minerals. Lanthanum metal is usually obtained by reducing the anhydrous fluoride with calcium.
