What drives GHG emissions from copper production ...
Nov 24, 2016 · A large open pit copper mine may use in the order of 200,000 L/d of diesel, with an emissions factor of about 2.7 kg CO2 e/L, resulting in 200,000 t CO2 e/y of emissions. That’s typically around 2 – 4 t CO2e/t Cu produced.
Impacts of copper mining on people and nature | Danwatch
For almost 100 years, Zambia has been highly dependent on copper and the mining industry, and the country is living proof that progress leaves its mark on both the environment and people’s health. Land degradation. Increased deforestation. Water and air pollution from particles of sulphuric acid, which severely affect those residing near mines.
Preliminary review of mine air pollution in Zambia ...
Thus in case of the copper mine air pollution effects, other minor pollutants such as oxides of nitrogen, including the secondary pollutant like ozone become significant as they can contribute to poor plant growth. The particulate matter effects on the growth and development aspects of plants are dependent on the physical and stone nature of PM.
Toxic Air Pollution from Copper Smelters Challenged ...
Oct 10, 2003 · The Environmental Protection Agency (EPA) is failing to protect communities and the environment from toxic air pollution emitted by copper smelters, environmental groups argued today. The U.S. Court of Appeals for the District of Columbia heard oral arguments in a case (Docket # 02-1253) challenging EPAs inadequate regulations for controlling toxic air emissions from primary copper smelters.

Environmental impact of mining - Wikipedia
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 …
Is Recycling Copper Good for the Environment? | Sciencing
Mining of copper produces dust and waste gases like sulfur dioxide, which contributes to air pollution. While miners minimize this pollution by trapping sulfur dioxide gas and using it to make sulfuric acid, the process of recycling copper rarely contributes to gas emissions that can pollute the environment.
What is Sulfide Mining? | Mining Action Group
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.
