copper mining air emissions
Mining Copper Ore affects the environment, in many negative ways. Firstly, it uses land, so animals and plants are usually moved or plowed over.

Washington DC — 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.
Cement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility's air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.

Emissions from primary copper smelters are principally particulate matter and sulfur oxides (SO x ). Emissions are generated from the roasters, smelting furnaces, and converters.
The proposed Black Butte copper mine near White Sulphur Springs moved one step closer to reality this week when the state issued a draft air quality permit. That has sportsmen's groups worried.
Heavy metal pollution is caused when such metals as arsenic, cobalt, copper, cadmium, lead, silver and zinc contained in excavated rock or exposed in an underground mine come in contact with water. Metals are leached out and carried downstream as water washes over the rock surface.
On June 12, 2002, the U.S. Environmental Protection Agency (EPA) promulgated final air toxics standards for the Primary Copper Smelting major sources. Primary copper smelting is the industry which refines copper sulfide ore concentrate from mined ore to produce anode grade copper, using pyrometallurgical processes.
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.

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 States.
In 2016, the direct emissions of copper mining industry amounted to almost 5.9 million metric tons of CO2 in Chile. The Statistics Portal. Statistics and Studies from more than 22,500 Sources.
Independent studies show many vectors of pollution, and combined they create a significant risk of contaminating the Boundary Waters.Sulfide-ore copper mining is a risky type of mining that has never been done before in Minnesota.
One type of pollution attributed to air emissions is acid rain. The smelting of sulfide ores results in the emission of sulfur dioxide gas, which reacts chemically in the atmosphere to form a sulfuric acid mist.
Background Zambia's major economic activity is mining, and as at 2005, mining contributed about 65% of export earnings. Major minerals are Copper and Cobalt Copper production stands at 465,000 mt, and is expected to reach about 700,000 mt by 2010. 2 big copper mines (new) to being developed, and several small ones.
The debate is the latest front in a fight among environmentalists, the mining industry and government officials over how to properly oversee and control air pollution from mines.
