source:eurekalertCrystals doped with rare-earth (RE) ions exhibit very narrow linewidths of the optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range. RE-doped materials are widely used as laser media, phosphors, scintillators, in solar cells, etc.  Nowadays, the RE-based luminescence thermometry is successfully developing, demonstrating a wide working temperature range, high thermal sensitivity, and spatial resolution. In a magnetic field, some spectral lines split, and the magnitude of magnetic field can be determined by m...

source:birminghamRare Earth materials used in high performance magnets for electronic devices will be recycled in a new facility at the University of Birmingham.The plant is a major milestone in the commercialisation of rare earth magnet recycling technology in the UK, offering a complete re-manufacturing process, taking magnets from end-of-life electric motors, electronic waste and components, reclaiming the valuable neodymium, iron and boron they contain, and reforming it back into commercial-grade magnetic materials.Rare earth magnets play a critical role in electronics devices ranging from...

source:innovationnewsnetworkIn an article on rare earth elements (REE) we posted earlier this year, it was noted that “the 15 lanthanides are very similar chemically and, as such, are difficult to separate using traditional solvent extraction technologies. While this can be done, it is a very expensive process involving multiple circuits in a very large facility.”Efforts to innovate more efficient rare earth separation process solutions are underway to simplify, reduce costs, and demonstrate more efficient separation process solutions. Progress is being made in Canada.We are always interested ...

source:miningA recent study published in the Journal of Geophysical Research: Solid Earth, presents two novel machine learning techniques to identify new, deeply buried porphyry copper deposits by characterizing magma fertility.Fertile magma refers to magmas that can form porphyry deposits.According to the paper’s authors, their main objective was to improve traditional geochemical indicators plagued by high false-positive rates.To achieve such a goal, the researchers developed two algorithms, which they called ‘random forest’ and ‘deep neural network.’ They formulated the models using a globa...
