Mining Rare Earth Elements, the Environment, Tech, and the

Mar 28, 2020 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.
