    Acid mine drainage may offer rare earths

    Shane Lasley, Metal Tech News|Updated Jul 10, 2022

    Penn State scientists have developed a process that could transform acid mine drainage from an environmental liability that is costly to an asset that produces rare earths and other valuable minerals. "We are currently incurring costs just to treat the water, and in many cases, we are not even collecting all these minerals," said Sarma Pisupati, professor of energy and mineral engineering at Penn State. "Now we are able to turn what had been considered a waste product into a v...

  • Scientists look to coal for REE solution

    Rose Ragsdale, For Metal Tech News|Updated Jul 2, 2022

    As security concerns mount over the nearly total reliance of the United States on foreign sources of rare earth elements, mostly from China, researchers in public and private laboratories across the country are aggressively searching for ways to spur domestic production of these critical minerals in the face of rapidly growing global demand. Rare earths, which in reality are plentiful in natural settings, can be found most everywhere. But the prohibitive financial and environm...

    Pennsylvanian coal helped to fuel America's Industrial Revolution, and mines in the Keystone State have since provided a domestic source of iron ore, cobalt, nickel, and various other metals. Now, researchers at Pennsylvania State University have identified a potential motherlode of battery metals to feed into America's EV Revolution in waste left behind by more than two centuries of mining in the commonwealth. "Preliminary estimates indicate that waste left by coal mining...
