Major sources of pollution in the mining operations are unpaved roads, blasting, and dust explosion during loading. Apart from air pollution due to mining activities, Significant emission of fine coal particulates (PM1, PM2.5, and PM10), heavy metal dust (PM1, PM2.5, and PM10), are and gases such as NOx, NO2, CO, CO2, and …

Abstract. Mine tailings—the residue remaining after mineral processing—represent a serious risk to the natural environment, and the failure of tailing storage facilities has caused some of the ...

Operations and waste products associated with metal extraction and processing are the principal causes of environmental concerns about metal mining. Concerns include: Physical disturbances to the landscape. Soil and water contamination. Air …

Coal and Water Pollution. Published Dec 6, 2017. Table of Contents. Lakes, rivers, streams, and drinking water supplies are all heavily impacted by coal mines and power plants. Coal is more often associated with billowing smokestacks than it is with water. But virtually every stage of coal's lifecycle—from mining to processing to burning ...

Iron mining tailings raise several concerns regarding their deposition and the decommissioning of storage dams, particularly regarding the limitations of this substrate for plant establishment, including poor substrate aggregation and limited availability of nutrients. The objective of this study was to evaluate the effect of the interaction of …

1. Introduction and background1.1. Mine dust pollution and its environmental & health risks. As the world's resources continue to be exploited, mining activities are giving rise to increasing environmental damage and pollution, of which mine dust pollution is considered to be one of the biggest threats to environment and public …

A century of active mining at Iron Mountain took an environmental toll. The first documented consequence of mining was fish kills in the Sacramento River in 1899, followed by severe air pollution from the open-air heap roasting and smelters that stripped the land of vegetation near the town of Keswick along lower Spring Creek.

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 …

Such operations are significant noise and vibration sources inside and outside the mining dwellings. Noise pollution was found to be more eminent in Kono with 60.0% of the participants indicating that noise pollution from the mine as a result of mine blast was prevalent, 53.3% of the respondents in Rutile while 48.3% of the participants in ...

Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ...

Air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb …

Air quality management in mining is a complex task, mainly due to the wide range of source types, the fact that most are diffuse and highly variable in nature, difficult to measure, and site-specific in terms of silt and moisture contents. Environmental factors such as temperature, rainfall and humidity compound emissions uncertainties.

Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of …

161 (25%) workers felt that the mining has caused air pollution affecting their health slowly. 173 (25%) mine workers felt that mi ning is the cause of increase in diseases and misery (Chauhan 2004).

This review aims to summarize the toxicity of Mn mining pollutants in the environment as well as in humans, plants, and animals and describes the biological remediation strategies. This review also focuses on the environmental Mn pollution and the future aspects to control the Mn pollutants through biological remediation approaches.

Globally, metal mining is one of the biggest sources of air pollution. A UNEP study finds that artisinal gold mining to be the leading source of human-caused mercury emissions. Smelting of metals, including gold, is a primary source of arsenic emissions and other toxins globally. To extract metal, ore is placed in a smelter, a type of furnace.

The mathematical description of natural ventilation processes in quarries requires the updating of huge data bases. In order to describe air circulation in a quarry, the known mathematical model was adopted, which takes into account the process of thermal convection from natural as well as from artificial heat sources.

The pollution of As and Pb in the far northwest of the mining area was more serious, different from the pollution in the mining area. This pollution may come from the garbage of the villages at the sampling point. Compared with the distribution map of the Chengchao iron mine, the PTEs pollution of the ancient copper …

Similarly, the other iron ore mining countries undertake most of the "international responsibility" of environmental pollution while providing valuable and cheap primary resources to the rest of the world. Fig. 4 shows that South Africa has the largest value of unit GDP impact from mining iron ore, followed by Australia. Ukraine has the ...

Vehicular emissions (17.85% variance) and windblown dust through unpaved roads and over burdens (7.54% variance) are the other causes of air quality deterioration around the coal mining areas. Pollution prevention advanced mining technology and effective strategies as well as public awareness and education may be reasonable and …

Contamination is one of the major global health concerns, especially in China. China's rapid urbanization over the past decades has caused widespread urban water, air, and soil degradation. This study provides a complete assessment of the soil contamination caused by heavy metals in China's mining and smelting regions.

Therefore, a comprehensive understanding of the chemical, physical and biological processes is essential for assessing the extension and effects of air pollution around mining areas, which should be based on a holistic approach. This Special Issue of Atmosphere will open a broad debate on issues related to air pollution in mining areas.
