source:Mining TechnologyCoal may be a viable source of rare earth elements, according to a study, critical in the manufacturing of high-demand products like batteries and solar panels. The Clean Coal Technology research group at the University of Witwatersand, Johannesburg conducted research focussing on the chemical composition of coal. Using coal samples from Waterberg, the research group found that the total rare earths content in discard and standard product from the coal mine was above 225 parts per million (ppm). This concentration is well above the cut-off grade of 130ppm for ...

source:natureThe fermented drink kombucha seems about as far away as possible from the mining of heavy metals. But Alexa Schmitz, chief executive at the biomining company REEgen in Ithaca, New York, sees parallels between her firm’s bacteria-based product and the tangy beverage.REEgen’s bacterial ‘soup’ dissolves ground-up rocks, waste electronic components and other solids that contain rare-earth elements — metals that have valuable conductive, magnetic and fluorescent properties and that are used in everything from mobile phones to wind turbines. The metals impart strength and hardness to al...

source：The Chemical EngineerRESEARCHERS at Penn State University, US, have developed a mussel-inspired nanocellulose coating (MINC) that can extract neodymium – a critical element used in clean energy technologies – from secondary sources such as industrial wastewater without using a high amount of energy. Playing a vital role in the production of lightweight, efficient batteries, and as essential powerful magnetic components in wind turbines, rare earth elements (REEs), including neodymium, are in high demand. Despite their name, many REEs are actually common in the Earth'...
