source:Eurasia ReviewRare earth elements are hard to get and hard to recycle, but a flash of intuition led Rice University scientists toward a possible solution. The Rice lab of chemist James Tour reports it has successfully extracted valuable rare earth elements (REE) from waste at yields high enough to resolve issues for manufacturers while boosting their profits. The lab’s flash Joule heating process, introduced several years ago to produce graphene from any solid carbon source, has now been applied to three sources of rare earth elements — coal fly ash, bauxite residue and electr...

source:Phys.orgSuperconductivity refers to the loss of electrical resistance of a material and requires extremely low temperatures (A breakthrough has been made with hydrogen-rich compounds (called hydrides) containing rare earth or alkaline metals, which display room temperature superconductivity at high pressures (100–200 GPa). These metal hydrides have cage-like structures of hydrogen atoms stacked on top of each other enabling them to withstand the high pressures required for the superconductivity phenomenon. Many of the crystal structures and compositions for these hydrides have been pred...

source:The West AustralianTaruga has tabled a series of exciting shallow rare earths drill hits with some samples grading above 50 per cent heavy rare earths and above 30 per cent magnetic rare earths from surface at its Morgan Creek and Hydrothermal Hill prospects within the company’s Mt Craig project in South Australia. The mineralisation is soil and clay hosted within the regolith profile that the company says indicates a shallow ionic clay style rare earths deposit.A skarn alteration system has been identified at the company’s Hydrothermal Hill prospect that extends for over 300 metres in ...
