Environmental impact of iron ore mining -

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 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

Environmental Risks of Mining

ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012). There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA],

Hardrock Mining: Environmental Impacts

Hardrock mining is a large-scale industrial activity that takes place in the natural environment, potentially disturbing large amounts of material and land area. Hardrock mining generates large volumes of mining waste because of the high waste-to-product ratios associated with producing most ores. This page describes some of the potential environmental effects of hardrock mining.

Mines and environmental impact - SGU

When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process. This weathering results in the release of an acidic and often metal-rich leachate into the surrounding environment, known as Acid Mine Drainage (AMD). If the waste also contains buffering carbonate minerals, the problems are smaller. However, in
