Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
