LG Innotek develops eco-friendly magnet with strong power thru cooperation with domestic partner source:Aju Business DailySEOUL -- LG Innotek, the electric component unit of South Korea's LG Group, has teamed with a domestic permanent magnet producer to develop an eco-friendly magnet with strong magnetic power that can minimize the use of heavy rare earth metals, an essential component to maintain magnetic force at high temperatures.Magnets are mounted on vehicle motors, smartphone cameras, audio speakers, and wind power generators. China has been a major source of rare earths, but ra...

source:altenergymagA report by Adamas Intelligence predicts that if the global rare earth industry continues to exploit these resources in the same way, in three to five years demand will outgrow supply. This is worrying news for manufacturing, as a scarcity of rare earths would affect the production of high-tech products like electric vehicles and robots. Here, Claudia Jarrett, US country manager at automation part supplier EU Automation, discusses the importance of rare earths in manufacturing and how a circular economy model can help limit their use.According to the author of The Structure ...

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...
