Environmental impact of iron ore mining Wikipedia

Mining and processing. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,. Most iron ore is produced from open-pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant.

TENORM: Copper Mining and Production Wastes Radiation

Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres 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.Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice....
