source:Live scienceScientists have genetically modified a tiny bacterium to rapidly purify the rare-earth metals used in computers, electric car batteries and hard drives.The new technique, described in a paper published Dec. 6 in the journal Synthetic Biology, could one day replace the environmentally harmful methods currently used to separate these elements from the metals with which they're normally found, researchers said.Rare-earth elements (REEs), or lanthanides, include the elements dysprosium, terbium and neodymium and are found on the third group and sixth row of the periodi...

ource;PHYS.ORGA research team led by Dr. Yingying Zhang (Department of Chemistry, Tsinghua University) devised a scheme utilizing silkworms to produce strong, tough silk through feeding them with rare earth ion-modified diets. The rare earth ions can be incorporated into silk fibroin through feeding. And the incorporated ions are capable of forming ion-dipole and cation-π interactions with silk fibroin. These interactions are promising to tune the structures of silk to enhance its mechanical performance.Spectra analysis confirmed the successful incorporation of rare earth ions into silk fibers...

source:MiningNamibia Critical Metals (TSX-V:NMI, OTCQB:NMREF) has announced the successful completion of the pilot plant flotation test work for its 'Lofdal 2B-4' heavy rare earth project. The rare earths project developer said based on preliminary data, the pilot plant program confirms the reproducibility of the grinding and flotation regime for the Lofdal flowsheet and the ability to scale-up the design with confirmation of engineering design criteria. "We are extremely pleased with the completion of the flotation pilot plant test work, which has yielded highly positiv...
