Rare Earth Elements (Lanthanides): Selected End Uses Light Rare Earths (more abundant) Major End Use Heavy Rare Earth (less abundant) Major End Use Lanthanum hybrid engines, metal alloys Terbium phosphors, permanent magnets Cerium auto catalyst, petroleum
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 ...
Rare Earth Elements What are Rare Earths? The Japanese call them “the seeds of technology.” The US Department of Energy calls them “technology metals.” They make possible the high tech world we live in today – everything from the miniaturization of electronics, to the enabling of green energy and medical technologies, to supporting a myriad of essential telecommunications and defense ...
Rare earth elements (REEs) are a group of 15 elements referred to as the lanthanide series in the periodic table of elements. Scandium and yttrium, while not true REEs, are also included in this categorization because they exhibit similar properties to the lanthanides and are always found in the same ore bodies.
These Rare Earth Elements have long ago been abandoned for mining and processing here in the United States and are part of our reliance on Chinese sources of supply. What are Rare Earth Elements? Rare Earth Elements (REE) are a selection of 17 elements …
Rare earth elements ("REEs") are a set of seventeen chemical elements.They include the fifteen lanthanides plus scandium and yttrium. Scandium and yttrium are rare earth elements since they are often found in the same ore deposits as the lanthanides and have similar chemical properties.. Although they are called rare, rare earth elements are not extremely rare on Earth.
Uses of the Rare Earth Elements. The REE are essential raw materials for a wide range of applications, including metallurgy (metal refining and metal alloying), catalysts in the automotive and the petro-chemical industry, colouring of glass/ceramics, phosphors (LEDs, compact fluorescent lamps, flat panel displays), lasers, rechargeable solid state batteries (Ni-MH), fibre optics and others.
Rare earth elements (REE) were first discovered in 1788. However, global annual REE production and consumption was less than 5000 metric tons of rare earth oxides (REO) before the 1950s and, until the 1960s, they were even rarely used in our daily life [1]. Since the 1960s, rare earth

14-3-2018· Some analysts believe rare earth elements could be ‘the new gold’ and prices are soaring, but the supply chain remains complex and troubled. The market for rare earth elements (REEs) is set for massive expansion, with optimistic but feasible forecasts pointing to a doubling in global demand by as soon as 2020.

Although they are called rare, rare earth elements are not extremely rare on Earth.
The rare earth elements (REE) have attracted much attention in recent years, being viewed as critical metals because of China’s domination of their supply chain. This is despite the fact that REE enrichments are known to exist in a wide range of settings, and have been the subject of much recent exploration. Although the REE are often referred to as a single group, in practice each ...
