source：AsiaTimesTin mining tailings could contain commercial quantities of rare earths both US and China would be keen to tapJAKARTA – Rare earth, the experts like to say, is neither rare nor is it earth. But given its use in everything from smartphones to high-tech aerospace and defense systems, a potential buried treasure from the past may soon become the next big thing in Indonesian mining.Indonesia appears to have only modest proven amounts of the v valuable minerals, but much of what it does have is locked away in the rock waste, or tailings, left over from centuries of tin mining on the ...

source：The Market HeraldIonic Rare Earths (IXR) has announced results from its drilling program have continued to deliver thick, high-grade rare earth element (REE) mineralisation.The 3700-metre program began in July this year and is planned to increase the potential of the 26-kilometre long mineralisation corridor at the Makuutu Rare Earths Project in Uganda.Pleasingly, the results further reinforce the continuity of total rare earth oxide (TREO).Significant results include 15.1 metres at 703 parts per million (ppm) TREO from 5.5 metres, 9.6 metres at 1026ppm TREO from 7.9 metres, 10.1 metres...

source：All About CircuitsA joint research team based at the University of Geneva has successfully controlled the properties of artificial electronic structures, dramatically improving energy efficiency.It’s no secret that silicon-based electronics consume a large amount of energy. And as devices get more powerful and smaller, they burn through more power.This is problematic not only because using more energy translates to higher operating costs, but it also leads to higher CO2 emissions. Naturally, it’s something that has scientists and design engineers scrambling for a solution, and one area ...
