source:Green Car CongressAlthough the US has domestic REE resources, its supply chain is vulnerable due to dependence on foreign entities for separation and purification of these elements.“Biomining,” an approach that uses microbes to extract or separate target metals such as gold or copper from a variety of sources is not yet useful for REEs because of poor specificity and selectivity of the microbes for REEs.The EMBER program will leverage the diversity, specificity, and customizability of environmental microbiology to enable new biomining methods for the separation, purification, and conver...

source:Drives and Control MagazineTests have shown that the process can recover 98% of a motor’s rare-earth elements (REEs). It also halves time taken to recover the materials compared to other methods, because there is no need to demagnetise the magnets, nor to remove and disassemble them from the motor.The process is aimed, in particular, at motors used in in electric vehicles, most of which rely on powerful neodymium magnets containing scarce rare-earth metals such as neodymium and dysprosium. China dominates the supply of these materials and this has led to wide fluctuations in price and a...

source:Investasi KontanKONTAN.CO.ID - JAKARTA. PT Timah Tbk (TINS) masih terus mengembangkan mineral logam tanah jarang alias rare earth elements (REE). Sekretaris Perusahaan TINS Abdullah Umar mengatakan, saat ini pihaknya sedang dalam proses penjajakan dengan beberapa calon mitra yang memiliki teknologi yang terbukti bisa memproses rare earth tersebut.Pasalnya, proses pengolahan mineral logam ikutan bijih timah ini tergolong cukup panjang. Menurut Abdullah, rare earth perlu dipecah terlebih dahulu menjadi senyawa oksida, kemudian menjadi logam, hingga hasil akhirnya menjadi magnet. 'Kami...
