Acid mine drainage occurs when mining exposes sulfide-containing minerals, which react with air and water to form sulfuric acid. New technologies are being developed to recover valuable critical minerals from these acidic waters, cleaning them up in the process.
The U.S. Department of Energy announced $156 million in funding for a first-of-a-kind facility to extract and separate rare earth elements and critical minerals from unconventional sources like mining waste.
As rare earths and other critical minerals are key to manufacturing clean energy technologies here in America – such as solar panels, wind turbines, electric vehicles, and hydrogen fuel c...
