Rare elements are in abandoned coal mine drainage

Down a long gravel road, tucked into the hills in West Virginia, is a low-slung building where researchers are extracting essential elements from an old coal mine that they hope will strengthen the nation’s energy future.
They aren’t mining the coal that powered the steel mills and locomotives that helped industrialize America – and that is blamed for contributing to global warming. Rather, researchers are finding that groundwater pouring out of this and other abandoned coal mines contains the rare earth elements and other valuable metals that are vital to making everything from electric vehicle motors to rechargeable batteries to fighter jets smaller, lighter or more powerful.
