source:Phys.orgRare earth elements from ore are vital for modern life but refining them after mining is costly, harms the environment and mostly occurs abroad.A new study describes a proof of principle for engineering a bacterium, Gluconobacter oxydans, that takes a big first step towards meeting skyrocketing rare earth element demand in a way that matches the cost and efficiency of traditional thermochemical extraction and refinement methods and is clean enough to meet U.S. environmental standards.'We're trying to come up with an environmentally friendly, low-temperature, low-pressure...

source:The West AustralianFrontier Resources has launched an airborne magnetic-radiometric survey over its new Gascoyne rare earths project in WA to better define drill targets at the prospective tenure after it discovered ironstone outcropping at surface. Ironstone is known to host rare earths at the nearby world class Yangibana discovery owned by Hastings Technology Metals and Frontier wasted no time sampling its own ironstones with results pending.The company says it hopes the survey will light up some rare earth anomalies that it can sink the drill bit into come the new year. It could also...

source:DCDThe bioleaching process, developed by Coventry University and IT recycling specialist N2S, can capture precious metals like gold and copper which are in electronic waste, so they can be reused instead of going to landfill. Colt has been involved in a six month trial of the idea.Bugs retrieve metals“Using our unique biotechnology process, we can extract large amounts of rare earth and precious metals such as gold and copper – sometimes up to 40 percent of a technology circuit board is made of copper,' said Steve Morris, N2S managing director. 'These metals can then be re-intro...
