The intent of this report is to identify who may be most likely to be exposed to wastes at small abandoned uranium mines, and where the greatest risks may lie. Technologically Enhanced Naturally Occurring Radioactive Materials in the Southwestern Copper Belt of Arizona (PDF) (124 pp, 8 , 402R99002)
Radioactive materials are present in many soils and rock formations, and consequently in the water that comes into contact with them. Extraction and processing of these resources may expose or concentrate naturally occurring radioactive materials naturally occurring radioactive materialsMaterials found in nature that emit ionizing radiation that have not been moved or concentrated by human

Mining waste; phosphate rock mining, beneficiation, and processing waste; and uranium waste are three of the six special wastes identified. October 21, 1976 Congress passes the Resources Conservation and Recovery Act (RCRA) (Public Law 94580) which requires EPA to develop regulations governing the identification and management of hazardous waste.
Processing rare earth minerals involves the separation and removal of uranium and thorium, which results in TENORM wastes. For detailed information and publications about rare earths, including statistics about domestic and international mining and use, see the Geological Survey Rare Earth Minerals Information page.
6 Copper mining, Production Wastes and the Environment As with other forms of mining, the control of operations varies considerably from country to country. Sadly, third world mining operations continue to present varying degrees of hazard to the health and
BHP is proposing a significant increase of copper production at the Olympic Dam mine to up to 300,000 tonnes a year. The Minister for Energy and Mining and Minister for Planning have declared this proposal a major development under the Development Act 1993 .
This particular training course is based on a Safety Report on Occupational Radiation Protection in the Uranium Mining and Processing Industry (SR100), which has been developed as part of the IAEA programme on Occupational Radiation Protection to provide for the application of its safety standards in implementing a graded approach to the protection of workers against exposures associated with
TENORM: Copper Mining and Production Wastes Radiation Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The States Ores that contain copper in the are typically mined in large, openpits. Copper processing facilities are usually located near mining or
Background Zambias major economic activity is mining, and as at 2005, mining contributed about 65% of export earnings. Major minerals are Copper and Cobalt Copper production stands at 465,000 mt, and is expected to reach about 700,000 mt by 2010. 2 big copper mines (new) to being developed, and several small ones.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 tons of solid waste for every 1 ton of aluminum produced.
Naturally Occurring Radioactive material, natural materials contain radioactive elements (radionuclides), known as NORM. The earth''s crust is radioactive. Information from the World Nuclear Association, the global privatesector organization that seeks toprovide information on nuclear power, nuclear energy, Chernobyl, uranium, nuclear waste management.
TENORM Copper Mining and Production Wastes Radiation Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the united states there is a broad range of tenorm concentrations in copper mining wastes for more information, see the epa report to congress, wastes from the extraction and beneficiation of metallic ores, phosphate rock, asbestos
Mining Waste. Mining wastes include hard rocks, gravels, clays, pebbles, sands, limestones, chalks, siftings of fine fractions, dump tailings of flotation concentration of ferrous and nonferrous metal ores, sulfur ores, apatitenepheline concentrates, coal wastes, halite flotation wastes, screenings of phosphorite, phosphoric ore fines, etc.
Mining activities are not new and indeed may have started in Neolithic (Chalcolithic) times to obtain the first metals for tool fabrication (Reardon 2011). In the Classic Greece and in the Roman Empire, many mines were exploited for production of iron, lead, copper, gold, and other metals.
