Gold mining is also responsible for releasing large amounts of mercury into the Amazon''s air and water.
• Copper''s use averages out at around 140300 kg per capita in developed countries • Copper along with oil and gold are among the most traded commodities. • Copper doesn''t break down in the environment, leading to its accumulation in plants and animals. • Absorption of some copper into the body is essential for human health.
Water in the mine containing dissolved heavy metals such as lead and cadmium leaked into local groundwater, contaminating it. Longterm storage of tailings and dust can lead to additional problems, as they can be easily blown off site by wind, as occurred at Skouriotissa, an abandoned copper mine in Cyprus.

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This smallscale form of gold mining has little effect on the body of water, but the largescale practice of mining gold from ore can have tremendous negative effects on water quality.
About 2 million tons a year are reclaimed by recycling. Today copper is mined as major deposits in Chile, Indonesia, USA, Australia and Canada, which together account for around 80% of the world''s copper.

These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts.
Dec 03, 2016· Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil [2]. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways..
