Source:Popular MechanicsThe viability of a renewable energy future relies on the ready supply of REEs, or rare-earth elements. There are 17 REEs in the periodic table and, though the name suggests otherwise, they are actually plentiful in the earth’s crust. The challenge is that these elements are not often concentrated in ore deposits, which makes them expensive and unreliable as an extractable resource for domestic use or export. This in part explains the shortage of these materials being extracted in the United States.Two of these rare-earth elements, neodymium (Nd) and dysprosium (Dy), are...

Source:ScienceAlertRare earth elements are essential for building everything from smartphones to solar power plants, but extracting them from the ground comes with a high cost in terms of expense, effort, and environmental impact. That could be about to change.Researchers have discovered a new way to get some of these elements out of phosphate rock waste (or phosphogypsum) in what could be a huge boost for clean energy development.The trick is using organic acids produced by bacteria to do the hard work of extracting rare earth elements (REEs) from phosphogypsum. The researchers tried a number...

Source:ForbesAlmost all technological products we use on a daily basis contain a group of elements known as the rare-earth metals. Abundant in technology and deemed by US Department of Energy as 'technology metals' due to the fact that they are used in all sorts of technologies ranging from computers and screens, networks, MRIs, batteries, magnets, automobiles and various types of special optical glasses, as well as a catalyst for oil refining. As a matter of fact, this a small sampling of examples, and the list goes on virtually touching every industry and modern technological devices...
