source:EastMojoMore than ten years ago, the so-called “rare earth crisis” highlighted the fragility of the supply chain of these metals, which are crucial for the transition to a carbon-neutral economy. Most of the world’s supply of these minerals comes from a handful of giant ore deposits, but we still know little about how these deposits formed.Despite the name, the rare earths are relatively widespread in Earth’s crust, compared with elements such as gold and platinum. Large, concentrated deposits suitable for mining, however, are much more scarce.To understand how these deposits form, we r...

Japanese dentists pay more for dental crown ingredient palladium due to economic sanctions on Russia source：EconoTimesapanese dentists are now paying far more for palladium, a rare earth metal that is an essential ingredient for making dental crowns, due to economic sanctions imposed against Russia due to its Ukraine invasion.Russia accounts for about 40 percent of the global palladium production.The price of the alloy containing palladium has skyrocketed over fears of supply chain disruptions as a result of the sanctions.In mid-December, the purchase price of palladium per 30 grams was 7...

source:The West AustralianFrontier Resources has scooped up a suite of high-grade rare earths from a 134-piece rock chip sampling program at its Gascoyne rare earths project in Western Australia, with the best result coming in at over 8 per cent total rare earth oxides, or “TREO”. The campaign was aimed at testing a number of compelling targets hosted within a geological terrain that boasts multiple world-class discoveries.Other notable results include 6.44, 5.27, 4.32 and 4.16 per cent TREO.Notably, over 54 of the bagged samples returned rare earths grades of over 0.1 per cent and 31 boasted ...

Ames Lab, Texas A&M team develop AI tool for discovery and prediction of new rare-earth compounds source:Green Car CongressResearchers from Ames Laboratory and Texas A&M University have trained a machine-learning (ML) model to assess the stability of new rare-earth compounds. The framework they developed builds on current state-of-the-art methods for experimenting with compounds and understanding chemical instabilities. A paper on their work is published in Acta Materialia.The approach is based on machine learning (ML), a form of artificial intelligence (AI), which is driven by co...
