2021-1-13 Increasing rare earth mining outside of China has reduced China’s global share of mining, down from 97.7% in 2010 to 62.9% in 2019. But mining is merely one piece of the puzzle. Ultimately, the large majority of rare earth refining, 80%, resides in China. Therefore, even rare earths mined overseas are sent to China for final processing.
