Molecular containers for the extraction of rare earths: New research project "SE-FLECX" started
Rare earths are in great demand because they are required for the manufacture of many high-tech products. However, their extraction from ores is expensive and often polluting. Experts from research and industry, coordinated by the Helmholtz Institute Freiberg for Resource Technology, are currently testing whether so-called calixarenes could be used as alternative extraction agents in industrial separation processes. Due to their special chemical [...]

Recycling of rare earths in the Harz planned
Recycling of rare earths planned in the resin Since their market launch in the late 1980s, sintered neodymium-iron-boron magnets have been used in many technical applications due to their extremely high energy density. However, there are no industrial recycling processes for these magnets. To change this, a consortium with the participation of the Clausthal University of Technology has launched the "Rare Earth Magnet Recycling" (SEMAREC) project [...]

Research at TU Clausthal: Recycling for high quality magnets
A research project at the Clausthal University of Technology relies on the magnetic material neodymium-iron-boron (NdFeB). The aim is to extract from production and consumer waste that contains rare earths with NdFeB. According to the TU Clausthal, there are no industrially implemented recycling processes for these magnets. Clausthal-Zellerfeld. To solve this problem, a consortium consisting of [...]

Thuringian researchers want to establish recycling of rare earths in this country
Metals of the so-called rare earths are found in most electronic devices today. The Thuringian researcher Ralf Müller wants to promote the recycling of such materials in this country. Weimar. Who likes to forego quality of life - most people take electricity from the socket as a matter of course, as do using a mobile phone. But for all of this to work smoothly, [...]

China is making rare earths attractive again
March 13.03th, 10:21 am Hasso Bergmann Not a day without new news from China on the economic situation and the government's measures. For us there is not a day without Dax records and discussions about the consequences of the financial repression and Draghi's bond purchase program that has now begun. As strange as it may look in the eyes of the Greeks - with a few exceptions the world experiences [...]

Price recovery for strategic raw materials
February 17.02th, 10:26 am Hasso Bergmann After Beijing had already tilted its export quotas at the beginning of the year, the export tax is also set to fall as part of the WTO ruling at the beginning of May. This ranges between 15 and 25% depending on the metal. Such a measure could well put the prices under pressure, writes the Frankfurter Tradium GmbH in its latest market report. However, [...]

Rare earths: Russia wants to compete with China
October 17, 2014 Darja Kesina, RBTH Russia is entering the market for rare earth metals, which are coveted around the world. So far the Chinese have dominated there. A unique mining technology developed at the Ural Federal University could help change that. Scientists from the Ural Federal University have developed a sorbent that enables the extraction of rare earth metals [...]

Öko-Institut calls for recycling system for rare earths
Whenever a hard drive or DVD player ends up in the garbage in Germany, rare earth metals are lost. This waste is unacceptable for the Öko-Institut. It calls for a recycling system for the expensive raw material. A small hard drive from Toshiba: Rare earths are often found in the high-performance magnets of the small motors. When scrapping, [...]

Improve the recycling of rare earths in electric motors
09.07.2014/09/17, XNUMX:XNUMX AM | Science | Author: idw | For the recycling of rare earths from permanent magnets in modern and highly efficient electric motors, sustainable recycling concepts must be developed in the coming years. The motors of industrial applications are not yet collected and disposed of separately at the end of their life; the potential for the recovery of the rare earths is thus not increased. This results in [...]

Rare earth clean and cheap?
08.07.2014/2/XNUMX - Kevin Bullis The start-up Infinium wants to make COXNUMX-intensive processes in metal production more environmentally friendly. In a laboratory building across from a yoga studio in an office park in Natick, near Boston, Adam Powell holds up a shiny white ceramic tube. This is the key to manufacturing much-used metals much cheaper and, above all, more ecologically, he says. Powell [...]
