Ores that contain copper in the us 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.

Material adapted from hudson tl fox fd and plumlee gs 1999 metal mining and the environment p 7202731353839 published by the american geosciences institute environmental awareness series modern mining operations actively strive to mitigate potential environmental consequences of extracting metals and such operations are strictly regulated in the united.

The impact of mining and smelting of metal ores on environmental quality is described mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material in the metal industry production of cu pb and zn causes the greatest degradation of the environment.

Have you ever wondered just how sulfideore copper mines pollute their surrounding environments its a good question because in order to understand the environmental impacts to the boundary waters canoe area wilderness and voyageurs national park we must first understand all of the ways sulfideore copper mining can cause harm to the surrounding lakes streams wetlands and.

The ratio of the amount of ore generated in a mine compared with the waste rock removed is quite high for instance in copper mining there are approximately 99 t of waste rock and tailings per ton of copper generated environmental mining council of british columbia and british columbia wild 1996.

Mining remains an essential and growing part of the modern industry by some estimates it makes up nearly 45 of the total global economy and mineral production continues to increase as demand for raw materials grows around the world however many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.

Mining can become more environmentally sustainable 1 by developing and integrating practices that reduce the environmental impact of mining operations these practices include measures such as reducing water and energy consumption minimizing land disturbance and waste production preventing soil water and air pollution at mine sites and conducting successful mine closure and reclamation.
