Lutetium


Lutetium exists in low concentrations (from 0,05% to 1%) in many rare-earth minerals, such as xenotime, gadolinite, samarskite, fergusonite and euxenite. Most of the lutetium oxide is commercially obtained from monazite, where the concentration of the element does not surpass 0,003%. Usually, lutetium is obtained as a by-product during the extraction of another rare earths as cerium and thorium. The largest monazite deposits are located in India, Brazil, Africa, Australia and USA.
