摘要

THE U.S. DEPARTMENT of Energy's (DOE) National Energy Technology Laboratory (NETL) has found high rare-earth element (REE) concentrations in coal samples taken from the Illinois, Northern Appalachian, Central Appalachian and Rocky Mountain Coal basins and the Pennsylvania Anthracite region. These highly concentrated samples are greater than 300 parts per million (ppm).
