souce:PNASSignificanceRare earth elements (REEs) are one of the critical global strategic resources. The sharply increasing demand for REEs leads to their overexploitation and environmental pollution. Recycling REEs from their second resources can achieve resource utilization and waste treatment. Pyrometallurgy pretreatment combined with acid leaching is efficient for recycling REEs. Unfortunately, due to the uncontrollable components of wastes, many trials were required to obtain the optimal parameters, leading to a high cost of recovery and new environmental risks. This study applied machine...

source:tech exploristRare earth elements (REE) play a key role in clean energy. It is vital to producing lightweight, efficient batteries and essential components in wind turbines.ntrarily, traditional methods of extracting these metals cause environmental problems such as habitat destruction, water and air pollution, and the high energy requirements for extracting and processing these elements.Penn State researchers used mussel stickiness as inspiration to find a solution to this conundrum. Researchers have created a novel mussel-inspired nano cellulose coating (MINC) by imitating this natura...

source:cowboy state dailyAnother day, another huge Wyoming rare earth discovery.The Cowboy State is fast becoming ground zero for a modern-day gold rush for rare earth elements long kept in a Chinese stranglehold.Earlier this year, Ramaco Resources announced it had found an unconventional deposit of rare earths that could be worth upward of $37 billion, based on an economic analysis by the Wall Street Journal.A company in Upton, Wyoming, is meanwhile setting up shop on a large rare earth deposit with a novel, developing a new process that promises to speed rare earth processing and make it dra...
