How Rare-Earth Mining Has Devastated China's Environment
The mining of rare earth metals occurs mainly in southeastern China, in provinces like Jiangxi and Fujian. But there is also mining as north as Inner Mongolia and as west as Sichuan. Over the last decade and a half, China has also moved to obtain exclusive mining rights in African countries in return for building big-ticket infrastructure

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.
