copper mining air emissions

  • What drives GHG emissions from copper production

    11/24/2016· 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.

    copper industry may be found in chapter 10. AIR QUALITY Pollutants of Concern and Their Regulation Uncontrolled copper smelting processes emit large quantities of particulate matter, trace ele-ments, and sulfur oxides, which can have adverse effects on human health. Sulfur dioxide (SO 2), and the sulfates and sulfuric acid aerosols it forms

  • Preliminary review of mine air pollution in Zambia

    9/1/2019· Mine air pollution in Zambia, which is largely due to SO 2 and PM, both fine and ultrafine (PM 10, PM 5.0, PM 2.5 and PM 0.1) emissions has been a topical issue since commercial mining started in the 1920s in the Copperbelt region of Zambia. However, very few studies have been undertaken to chronicle the extent of damage to the environment and harm to human health.

  • Toxic Air Pollution from Copper Smelters Challenged

    10/10/2003· Copper smelters operating in the United States emit staggering amounts of toxic pollution: more than 50 tons of lead, 30 tons of arsenic and 20 tons of selenium each year.

  • CO2 emissions of global metal-industries: The case of copper

    As the demand for copper increases, its ore grade is expected to decrease, and the energy required for copper production and the related CO 2 emissions are thus expected to increase fairly rapidly

  • Copper production & environmental impact

    • A computer contains around 1.5 kg of copper, a typical home about 100 kg and a wind turbine 5 tonnes. • Copper has low chemical reactivity. In moist air it slowly forms a greenish surface film called patina; this coating protects the metal from further attack. • Copper is easily alloyed with other metals.

  • 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.

  • CO₂ Emissions Sustainable Copper

    7/2/2020· The transition away from coal has reduced air pollutant emissions by 6,000 tonnes—one million tonnes of CO2 annually. Retiring our power plant is an important milestone for our business because it will immediately reduce our emissions to the local airshed, and I’m proud Kennecott is a leader in pairing our electrical needs with carbon

    Sources of Copper Emissions The following sources of atmospheric emissions of copper and copper com- pounds were investigated: Copper mining and milling Primary copper Roasting Reverberatory furnace Converters Materials handling Secondary copper Scrap production Wire burning Sweating furnace Blast furnace Smelting, reverberatory Smelting, rotary Iron and steel Blast furnace Open hearth furnace Basic oxygen furnace Electric arc furnace Gray iron foundries Miscellaneous copper

  • Reducing GHG global emissions from copper refining

    3/1/2020· Using the carbon emission factor for oil combustion provided by IPCC (2014) for the different types of ships that transport copper concentrates from Chile, it is possible to obtain an expression for the GHG emissions generated (expressed in CO2-eq tons) by importing country “l” from the gangue transported through the Panama Canal − C l − plus the gangue transported through routes different to

  • Zero Emissions Mines Have Started International Copper

    7/21/2020· Of course renewable energy is just one part of the zero emissions puzzle facing miners. Mining is responsible for 10% of the country’s energy use, so cutting back not only makes environmental sense but financial as well. Transforming the mining sector-and copper in particular-is likely to take a lot more effort though.

  • Effects of Mining on Air Lutopan Mining Activity

    8/6/2012· The gold mining industry is one of the most destructive industries in the world, because of all of the toxins that are released into the air. Acid rain and smog are also some side-effects of mining. Every year, 142 million tons of sulfur dioxide is emitted into the atmosphere because of smelting. That’s 13% of total global emissions.
