source:Mining.comScientists from the University of Exeter and the British Geological Survey (BGS), alongside a team of institutions across Europe, have developed a new 3D geological model designed to guide the exploration of rare earth elements.The model targets alkaline igneous systems, which host many of the world’s REE deposits.In a paper published in the journal Economic Geology, the researchers point out that despite the growing importance of these essential raw materials, exploration models for REE are comparatively less developed than those for major and precious metals such as iron, co...

source:AZO materialsLaser powder bed fusion (LPBF), a powder bed-based additive manufacturing (AM) technology, has been used to create complicated geometric metallic components. Due to the increased need for producing high-strength lightweight components, the application of LPBF to Al alloys has recently received a lot of attention.As previously mentioned, the Al-Si system is the most popular Al alloy for LPBF. Although the post-heat treatment can increase the ductility of Al-Si alloys produced by LPBF, the strength gradually begins to decline due to the coarsening of the fine cellular eutecti...

source:Borneo BulletinA handful of postage-stamp nations in the South Pacific launched an uphill battle this week against the deep-sea mining of unattached, fist-sized rocks rich in rare Earth metals.The stakes are potentially enormous.Companies keen to scrape the ocean floor five to six thousand metres below sea level stand to earn billions harvesting manganese, cobalt, copper and nickel currently used to build batteries for electric vehicles.But the extraction process would disfigure what may be the most pristine ecosystem on the planet and could take millennia, if not longer, for nature to ...
