Environmental impact of iron ore mining - Wikipedia

The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing, ground excavation, and from equipment t

What Is The Environmental Impact Of The Mining Industry ...

25/04/2017  Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining

Environmental impact of mining - Wikipedia

The environmental factors of the coal industry are not only impacting air pollution, water management and land use but also is causing severe health effects by the burning of the coal. Air pollution is increasing in numbers of toxins such as mercury, lead, sulfur dioxide, nitrogen oxides and other heavy metals. This is causing health issues involving breathing difficulties and is impacting the wildlife around the surrounding areas that needs clean air to survive. The future of air pollution remains unclear as the Environmental Pr
