DISPERSION MODELLING OF AIR POLLUTION FROM OPEN PIT COPPER MINE ABSTRACT Copper mining operations have increased in Iran in the past decades due to price increases and potential for creating jobs in developing countries. Iran consists of many copper mines. The mining
What To Do About Water Pollution in the Mining Industry: Water is a limited resource on this planet. Regardless of this fact, it is a desired and necessary resource in every and industry, but yet there are some industries where water is wasted and polluted with no further thought or action.
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 Court of Appeals for the District of Columbia heard oral arguments in a case (Docket # 021253) challenging EPA''s inadequate regulations for controlling toxic air emissions from primary copper .
The reason is very simple. The increased mining activity that was greenlighted by the Division of Air Quality would increase RTK''s overall emissions of nitrogen oxides by 54 percent and its particulate emissions by 66 percent. That''s according to the company''s own documents.
Efforts to combat urban air pollution, such as emission controls on cars, are wellknown examples of regulations developed under CAA. Examples of miningrelated situations that are covered by CAAbased regulations include dust emissions that accompany operations or tailings disposal in impoundments, exhaust emissions from heavy equipment, and ...

the 1980 Copper Strike, "Journal of Air Pollution Control, vol. 33,. though fossilfueled electric powerplants are the major source of S0 2 emissions in the United States, smelters contribute significantly to total emissions in the sparsely popuIated copperproducing areas of the West (see table 8l). Fugitive emissions from furnaces and ...
There is a broad range of TENORM concentrations in copper mining wastes. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailings tailingsThe remaining portion of a metalbearing ore after some or all of a metal, such as uranium, has been extracted.. Leaching and ...
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 carbon which have ...
Dec 17, 2016· Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
Aug 24, 2017· The mining and processing of nickelrich ores can generate high loadings of dust in the air, that contains high concentrations of potentially toxic metals, including nickel itself, copper, cobalt ...
Aug 07, 2018· Mining air pollution. In the mining process a lot of activities are involved: drilling, blasting, hauling, collection, and transportation. Some mining methods may have significant environmental impact and public health effects during these activities, as miners have a huge and constant exposure to several air pollutants.
AIR POLLUTION ASPECTS OF EMISSION SOURCES: PRIMARY COPPER PRODUCTION A BIBLIOGRAPHY WITH ABSTRACTS INTRODUCTION The Air Pollution Technical Information Center (APTIC) of the Office of Air Quality Planning and Standards prepared, selected, and compiled the abstracts in this bibliography.
Lead and air quality monitoring . Mount Isa Mines operations have a number of sources of emissions to air, including the lead smelter stack, copper smelter stack, and fugitive emissions from mining, ore transport, ore preparation, sintering and smelting operations, and waste disposal.
Copper compounds can break down and release free copper into the air, water, and foods. ... 6 Copper mining, Production Wastes and the Environment . As with other forms of mining, the control of operations varies considerably from country to country. ... Surface water pollution. Acid mine drainage invades a water course.
The purpose of this study was to collect information on the air emission sources of copper and copper compounds. These sources were characterized by copper emission quantities and stack parameters (, height, flow, and temperature) on individual plants, where possible. Each point source within the plant was char acterized.
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.
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 chemical nature of PM.

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.
