Rare Earths Deposits

Rare-earth element - Wikipedia

Rare-earth element cerium is actually the 25th most abundant element in Earth's crust, having 68 parts per million (about as common as copper). Only the highly unstable and radioactive promethium "rare earth" is quite scarce. The rare-earth elements are often found together. The longest-lived isotope of promethium has a half-life of 17.7 years, so the element exists in nature in only negligible amounts (approximately 572 g in the ent…

How rare are they? The term ‘rare earths’ was first used in the late eighteenth and early nineteenth centuries, to refer to minerals containing REE and some other metals, known deposits of which were rare – only subsequently did the name ‘rare earth elements’ come to be associated solely with the specific set of elements it denotes today.

Xenotime preferentially incorporates heavy rare earth elements (HREEs) while monazite incorporates light rare earth elements (LREEs). This is important because LREEs are much more readily available and therefore a xenotime deposit may be more valuable than a deposit of monazite. Bastnasite is found in carbonatites and pegmatites and refineries can acquire quantities of europium oxide, cerium ...
