source:/cleantechnicaChemistry was never really my strong point, and I can’t remember seeing neodymium and praseodymium (NdPr) on the periodic table in high school, but these rare earth elements (REE) are becoming more and more important for driving the future of the electric vehicle revolution. There are several local companies mining for rare earths in Australia, and Arafura Resources looks set to become a major player with its Nolans project in the Northern Territory situated 135 kilometres north of Alice Springs.Australia’s first nations people are benefiting from the project, as a “Native...

INL team develops efficient method for separating rare earth elements and transition metals in magnet scrap source:greencarcongressResearchers at Idaho National Laboratory have developed a dimethyl ether-driven fractional crystallization process for separating rare earth elements and transition metals. The process has been successfully applied in the treatment of rare earth element-bearing permanent magnet leachates as an atom-efficient, reagent-free separation method.The process begins with a magnet that’s no longer useful, which is cut and ground into shavings, said Caleb Stetson, lead ...

source:natureAbstractIn the early stages after larval settlement, coral spat can be rapidly overgrown and outcompeted by algae, reducing overall survival for coral reef replenishment and supply for restoration programs. Here we investigated three antifouling (AF) coatings for their ability to inhibit algal fouling on coral settlement plugs, a commonly-used restoration substrate. Plugs were either fully or partially coated with the AF coatings and incubated in mesocosm systems with partial recirculation for 37 days to track fouling succession. In addition, settlement of Acropora tenuis larvae w...

source:thewestOngoing exploration across a pair of prospects at Asra Minerals’ flagship Mt Stirling Project in WA has returned a clutch of notable rare earths and critical mineral results. The company has so far plunged over 1300 holes for 16,516m at the site and has now confirmed the widespread presence of rare earths, nickel, cobalt and scandium mineralisation in a shallow blanket of weathered rocks.Recent drilling at Asra’s Wishbone prospect returned a string of total rare earth yttrium oxides, or “TREYO” results grading over 200 parts per million within a 1.3 x .5km wide corridor.Initial a...
