Rare Earth Elements Geology. The international union of pure and applied chemistry includes scandium in their rare earth element definition. As concerns for energy independence, climate change, and other issues drive the sale of electric and hybrid vehicles, the demand for batteries made with rare earth compounds will climb even faster.
WHAT IS PLANNED IN THE BLACK HILLS? from sdcleanwateralliance.org Through the 1950s, south africa took the status as the world’s rare earth source, after large veins of rare earth bearing monazite were discovered there. The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium). Again, they are rarely found in extractable concentrations.
Rare earth elements became known to the world with the discovery of the black mineral “ytterbite” (renamed to gadolinite in 1800) by lieutenant carl axel arrhenius in 1787, at a quarry in the village of ytterby, sweden.
Rare earth magnet demand is expected to increase, as is the demand for rechargeable batteries. The most abundant rare earth elements are cerium, yttrium, lanthanum and neodymium 2. There is no fast way to open a new mining property. The elements from 57 la to 63 eu are considered as lrees, whereas the elements from 64 gd to 71 lu, including y are categorised as hrees.
