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.Uranium, which may be co located with copper ore, may also be recovered as a side stream, if economical.
