Substitution strategies for reducing the use of rare ...

In terms of the demand for rare earths for HTS wind turbines, first estimations indicate a very low quantity of about 2 kg REEs/MW. The main rare earth requested is yttrium, in the range of 0.1–0.8 kg/MW ( Wuppertal, 2014 ), but this could be substituted by lanthanum or cerium ( Buchert, 2011 ).

What is the most used rare earth element ...

The most abundant rare earth elements are cerium, yttrium, lanthanum and neodymium [2]. They have average crustal abundances that are similar to commonly used industrial metals such as chromium, nickel, zinc, molybdenum, tin, tungsten, and lead [1]. Again, they are rarely found in extractable concentrations.

Not So "Green" Technology: The Complicated Legacy of Rare ...

For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

Rare Earth Elements - PUB2911

Rare earth elements are divided into two groups, "light" and "heavy.". The "light" rare earths (LREE) are lanthanum, cerium, praseodymium, neodymium and samarium. The other nine lanthanides and yttrium comprise the "heavy" rare earths (HREE). Differences in the two groups are related to their chemical behavior which consequently ...

Rare earth elements: Mendeleev's bane, modern marvels

The REs are a family of 17 metallic elements formed by the group III (Sc, Y) and the lanthanide series (La–Lu). The name "rare earth" is misleading and does not represent a geological scarcity ( Fig. 1B) ( 71 ). The origin of this description lies in the occurrence of REs as a mixture of elements in minerals, generally at low concentration.
