Exposure to chronic high levels of copper can increase risk factors for lung cancer and coronary heart disease. Studies of copper mine workers both pre and post mortem have detailed the risk of chronic copper exposure and broken the risk up by parts of the copper mining processes ( smeltering, converting, plating) (11,12,13,14). Figure 3.
If they fail to reclaim the land, they may face a fine, be immediately stopped from mining, and be prohibited from getting future permits to mine. Many developing countries lack mining regulations and environmental problems associated with mining are still prevalent in those areas.
Jan 21, 2015· Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and, at low levels, air. Its average concentration in the earth''s crust is about 50 parts copper per million parts soil (ppm) or, stated another way, 50 grams of copper per 1,000,000 grams of soil ( ounces or pounds of copper per 2,200 pounds of soil).
communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment.

Ores that contain copper in the 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.
have, however, led to new operations also in other provinces. The main environmental problems associated with mines in Zambia are pollution of air, soil and water, geotechnical issues and land degradation. The contribution from old mining legacy sites have shown to be minor compared to current mining operations.
Sulfuric acid is sometimes produced when water interacts with tailings, or it can be a byproduct of ore processing. As a result, highly acidic water leaks from the tailings and disrupts aquatic life downstream. Tailings from copper and uranium mining often produce measurable levels of radioactivity.
Copper is ideal for electrical wiring because it is easily worked, can be drawn into fine wire and has a high electrical conductivity. Copper in the environment.
