Environmental impact of iron ore mining - Wikipedia

Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro

Effects of Mining on Air Lutopan Mining Activity

06/08/2012  The gold mining industry is one of the most destructive industries in the world, because of all of the toxins that are released into the air. Acid rain and smog are also some side-effects of mining. Every year, 142 million tons of sulfur dioxide is emitted into the atmosphere because of smelting. That’s 13% of total global emissions.

Physical Geology Today – The Environmental Impact of

When mining efforts necessitate deforestation of vast areas, silting of lakes and streams can occur as a result of the resulting increased erosion. The smelting of ore releases huge quantities of pollutants into the atmosphere. The extraction of metals from metal sulfide ores, for example, is estimated to be responsible for the annual emission ...

Environmental Impacts of Metal Ore Mining and

The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment. Copper mining produces extensive mine wastes and tailings and Cu smelting emits ...

Irresponsible Mining Damages the Environment -

Mining involves moving large quantities of rock, and in surface mining, overburden land impacts are immense. Almost all of the mined ore of non-ferrous metals becomes waste. A lot of areas are pock marked by thousands of small holes by people digging in search of precious minerals. Mining activities also may lead to erosion, which is dangerous for the land. It destroys river banks, and changes ...

Assessment of Environmental Impact of Iron Ore

However, mining of iron ore has copious negative impacts on the environment. As the mining method for Iron is usually open cast, it degrades natural landscapes, surface and ground water, flora and fauna, as well as the ambient air quality within the mining area and its environs. Water quality is contaminated due to surface runoff and leachate that are generated from large volume overburden and ...
