A process for producing a rare earth magnet comprises: an adhesion step of causing a diffusion element capable of diffusing inwardly to adhere to the surface part of a magnet material comprising a compact or sintered body of rare earth alloy particles; and an evaporation step of heating the magnet material in vacuum to evaporate at least a portion of the diffusion element having been retained ...
First, the process can extract rare earth elements from fly ash, producing a viable income stream for a utility or ash management company. Further, the process is such that other beneficiation such as ash use in concrete is not impacted.
Thorium is commonly found in the presence of rare earth metals in natural ores. The separation of the thorium is necessary to enable the transportation and purification of the valuable rare earth metals. Currently solvent extraction is the only viable process available to do this.
The current rareearth recycling research builds on Ames Laboratory's decades of rareearth processing experience. In the 1990s, Ames Lab scientists developed a process that uses molten magnesium to remove rare earths from neodymiumironboron magnet scrap. At the time, rare earth costs were low.
"The Rare Earth — Just how rare is Earthlike complex life?" How special are the circumstances that have allowed complex life like animals and mammals to develop on Earth? In this activity students systematically investigate the time frame for complex life to develop on Earth.
He and four coauthors are just finishing up the book Rare Earths: Science, Technology, Production and Use, which has taken him around the United States, Canada and France, visiting rare earth mines, smelters, manufacturing plants, laboratories and recycling facilities.
The Molycorp minerals mine is the only rare earth mine in production in the Western Hemisphere and produces 4 million tons per year of rare earth mineral elements, which are utilized in various energy efficient technologies.

Recycling rareearthcontaining products would provide a steady, domestic source of rare earths to manufacturers while also reducing waste. Currently, the main roadblock to recycling rare earth elements is the cost required to purify the mixtures obtained from consumer devices.
Texture and microhardness of MgRare Earth (Nd and Ce) alloys processed by highpressure torsion. ... The rare earth content in the Mg may also contribute to the activation of nonbasal slip by modifying the stackingfault energy (SFE) of the Mg matrix .
An acidfree dissolution rareearth magnet recycling process has earned a 2018 Notable Technology Development Award from the Federal Laboratories Consortium (FLC).
The goal of Innord Inc. is to develop and optimize the proprietary separation process of rare earth elements based on electrophoresis, for which it holds all the rights. Electrophoresis is the migration of charged species (ions, proteins, particles) in solution in the presence of an electric field.

Rare earth magnets inside permalloy brackets (pictured) can be recycled with an ORNLdeveloped process licensed by Momentum Technologies (credit ORNL). News release from Oak Ridge National Laboratory, September 2, 2016.
Rare Earths as Catalysts. REEs are fundamental ingredients in fluid catalytic cracking (FCC) catalysts. FCC is the process whereby crude oils are converted into gasoline and other products. The use of rare earthcontaining catalysts facilitates FCC, resulting in higher yields and purer end products than could otherwise be achieved.
A new rareearth magnet recycling process developed by researchers at the Critical Materials Institute (CMI) dissolves magnets in an acidfree solution and recovers high purity rare earth elements.
2017 was a challenging year for the rare earths sector, although "magnet metals" like neodymium and praseodymium enjoyed price gains.. Lack of production outside China continues to be an issue ...
"Rare earths" are a group of 17 chemically similar elements crucial to the manufacture of many hitech products. Despite their name, most are abundant in nature but are hazardous to extract.
Rare earths can be divided into "light" rare earths and "heavy" rare earths and both are present to varying degrees in all rare earth deposits. Rare earths are therefore recovered and processed together before sequential separation into individual rare earth elements.
