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 [...]

Coveted metals from old lamps
Bernd Schlupeck scientists in Saxony have developed a chemical process to obtain rare earths inexpensively from fluorescent sludge from lamp production and fluorescent powder from old tubes. Rare earths are not necessarily rare, but often expensive raw materials that are used in almost all high-tech products. "So, this is now the stirred tank where the phosphors are processed." Peter Fröhlich, [...]

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, [...]

How short are our metal raw materials?
Researchers determine supply risk for 62 important elements Whether gallium, chromium or rare earths - many metals are indispensable for modern technology. In the most comprehensive analysis to date, researchers have now determined the criticality of 62 elements where there is a threat of supply bottlenecks or shortages. As it shows, the supply risk is particularly high for metals, which [...]

NEW LAW Fight the electronic waste
By THORSTEN KNUF The federal government presents a draft law based on the EU model. Accordingly, dealers should be obliged to take back discarded electrical devices. By 2019, 65 percent of electronic waste should be recycled. A lot of old electrical appliances are stored in many basements or storage rooms - such as discarded televisions, refrigerators, vacuum cleaners, kettles or cell phones. Such devices must not be disposed of with normal household waste. [...]

Dealers have to take back old electrical appliances in the future
A new draft law by Environment Minister Barbara Hendricks (SPD) wants to oblige businesses in the future to take back old electrical devices when buying a new device of equal value. With the reform of the electrical law, the federal government is planning to recycle more valuable metals from old devices such as cell phones, toasters and modems. The new take-back obligation is intended for shops with more than 400 square meters of sales area and [...]

Researchers can filter rare earths from sewage
German middle class news | December 15.12.14, 21, 33:XNUMX pm Scientists want to recycle valuable substances such as rare earths with the help of algae. To do this, they filter industrial wastewater from spoil heaps. The metal ions of the valuable raw materials dock on the surface of the microalgae. Rare earths are used to manufacture high technology products such as smartphones and tablets. Scientists from the Friedrich Alexander University (FAU) gain the elements [...]
