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 sites, and conducting successful mine closure and reclamation

Particulates, SO 2 NO x, CO and hydrocarbon emissions are considered major air pollutants in mining areas. Out of these, particulates are a major hazard and mining authorities are giving utmost attention in controlling these by various suppressive and preventive measures.
Aug 10, 2018#0183;#32;Slumps, piles can be unstable, and experience landslides. In 1966, in Aberfan, Wales, a hill of mining debris famously collapsed onto buildings, resulting in
USEPA (2006) The environmental consequences of mining Iron Mountain became apparent only a few years after the start of open mining in 1896. Fish kills in 1902 in the Sacramento River, near the city of Redding, were the first documented effects, and shortly thereafter, several private lawsuits and an injunction from the Forest Reserve (precursor to the Forest Service) were served against
Material adapted from: Hudson,, Fox,, and Plumlee, 1999. Metal Mining and the Environment, p. 7,2027,3135,3839. 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
Apr 19, 2019#0183;#32;The Iron Range mining firm United Taconite has agreed to pay more than 500,000 to settle a federal lawsuit over air pollution from its processing plant in Forbes in northern Minnesota. The
1) The toxicity of metal can cause problems due to mercury, fluorine and also arsenic. These metals enter the food chain and affect all the animals in suit. 2) Mining also cause lung defects like Pneumoconiosis which is due to the inhalation of coal and other dust particles in the process of mining.
Over 5000 years of mining pollution have contributed to the river becoming an extreme environment, although the presence of chemolithotrophic organisms, such as ironoxidizing bacteria and sulfuroxidizing bacteria, are thought to be the true culprits to the river''s condition.
When unusually high amounts of iron exist in water, this is usually due to pollution related to construction or iron mining. Iron comes in several forms in water. It can be dissolved in the water or so heavy that it forms a precipitate or microscopic solid pieces suspended in the water. Scientists are experimenting with iron fertilization to reduce global warming by intentionally increasing the iron levels in seawater.
The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also cause water pollution of heavy metals and acid that drains from the mines.
The results from the various water quality test conducted revealed that there is a potential of surface and ground water pollution by iron ore mining.
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
Air pollution mining results in dust and also the air samples from mining environments that were testes had such high levels of silica, also the air contains radioactive elements because of the mining. Noise pollution creates noise and vibration from tipper trucks. Can cause hearing loss and anxiety not only for workers but people living nearby. Land pollution Miners dispose waste (burnt tyres and engine oil) on
Mine drainage is metalrich water formed from a chemical reaction between water and rocks containing sulfurbearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
