What Is The Environmental Impact Of The Mining Industry Air quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne. Lead, arsenic, cadmium, and other toxic elements are often present in such particles. These pollutants can damage the health of people living near the mining site. Diseases of the respiratory system and allergies can be triggered by the inhalation of such airb

Mining also causes water pollution which includes metal contamination, increased sediment levels in streams, and acid mine drainage. Pollutants released from processing plants, tailing ponds, underground mines, wastedisposal areas, active or abandoned surface or haulage roads, etc., act as the top sources of water pollution. Sediments released through soil erosion cause siltation or the smothering of stream beds. It adversely impacts irrigation, swimming, fishing, domestic water supply, and

The creation of landscape blots like open pits and piles of waste rocks due to mining operations can lead to the physical destruction of the land at the mining site. Such disruptions can contribute to the deterioration of the area's flora and fauna. There is also a huge possibility that many of the surface features that were present before mining activities cannot be replaced after the process has ended. The removal of soil layers and deep underground digging can destabilize the ground which

Often, the worst effects of mining activities are observed after the mining process has ceased. The destruction or drastic modification of the premined landscape can have a catastrophic impact on the biodiversity of that area. Mining leads to a massive habitat loss for a diversity of flora and fauna ranging from soil microorganisms to large mammals. Endemic species are most severely affected since even the slightest disruptions in their habitat can result in extinction or put them at high ri

TENORM: Copper Mining and Production Wastes Radiation Ores that contain copper in the U.S. are typically mined in large, openpits. 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 colocated with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice. Learn more about uranium mining. The production of copper typically includes the following processes: 1. Leaching 2. Solvent Extraction 3. Smelting

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. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailingstailingsThe remaining portion of a metalbearing ore after some or all of a metal, such as uranium, has been extracted.. Leaching and solvent extraction/electrowinning processes, as well as the practice of recycling raffinate at copper mines, may extract and concentrate soluble radioactive materials. In some cases, levels up to two orders of magnitude over background have been measured. View the report,TENORM in SW Copper Belt of Arizona, on the TENORM Resources webpagefor more information and specific measurements. Because the pyrite and sulfide minerals are in tailings piles, which have an exposed surface area, they may be susceptible to leaching of radio

Some wastes from copper mines can be reused. Mixtures of crushed waste rock have been used to construct embankments, fills, or pavement bases for highways. Some studies have shown that copper tailings can be used in bricks if pyrites are first removed.

EPA's Role

The Arizona Department of Environmental Quality (ADEQ) shared the results of radiological surveys with EPA on TENORM emanating from copper mines in mid1992. These surveys show that radionuclide concentrations vary, from nearbackground levels to above maximum contaminant levels, across the state, including increases of up to 100 times background levels for all radiochemicals tested except radon222. After reviewing the data provided by ADEQ, the EPA then examined the occurrence and distribut
