CRITICAL MINERAL RESOURCES
The mineral production that supplies many of these elements is concentrated in certain countries. In 2020, the United States was reliant on other countries for processed REEs, and in 2021, the United States mined <16% of the global rare earth element supply. China produces most of the global REE supply (Tse, 2011).
