Cornell engineers are pioneering a novel method for mining metals that are key to unlocking a sustainable future. By Chris Dawson. In the search for more sustainable energy technologies, many of the solutions humans are turning to – rechargeable batteries, massive wind turbines, electric cars, LED lighting – rely on what are known as rare-earth elements.
The process of mining REEs is ecologically devastating. Processing one ton of rare earth metals releases 2,000 tons of radioactive materials, carcinogens, toxic compounds, acids, and other pollutants into the environment. Since thorium and uranium often occur alongside REEs in nature, tailings from mines tend to be radioactive.
