Rare earth element (REE) mining and processing are large-scale industries that generate significant quantities of waste. In addition, the ores contain variable amounts of nontarget toxic metals, fluorine, and radionuclides. Past REE mining and processing therefore have led to significant environmental impacts in several countries.


One of the most extreme examples is Baotou, a Chinese city in Inner Mongolia, where rare earth mining poisoned surrounding farms and nearby …
