Environmental Impact of Steel - TheWorldCounts

Iron ore is the world’s third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil. 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 .

Recovery of Iron Values from Waste Manganiferous Iron Ore .

Indian iron ore - should be able to sustain the projected domestic steel demand for over 200 years [10]. The current iron ore re-sources of about 25 billion tones will last for 75 to 85 years as steel production touches 400 million tons by 2020. As the demand of iron ore is increasing, it is necessary to recover the resources from the mines .

Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.

Adherence to the constraints maps will reduce the effects of the DSO mining, but inevitable deterioration of habitat will still occur. Downstream effects on riverine habitats,

Iron is a stormwater pollutant and requires treatment

In 2002, eleven open pit mines were responsible for supplying 99% of the iron ore produced in the United States. The U.S. produced 5% of the world’s iron supply while consuming about 7%. The world production of iron ore in 2004 was 1.4 billion tons. China, Brazil, and Australia generated 57% of the global production.

Iron factories - pollution and displacement

More pictures water pollution. Health impacts. The factories dump their poisonous waste everywhere. (page 21) “Iron acts along with other carcinogenic heavy metals to increase cancer risk. The toxic effects of heavy metals are varied and may often manifest after a prolonged period, sometimes several years, as in the case of cancer.

Steel production & environmental impact

Iron ore. Iron doesn’t occur naturally. Being highly reactive, it combines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). Most iron ore is extracted through opencast mines.

Coal and Water Pollution | Union of Concerned Scientists

Coal mining. Mining operations can negatively impact water supplies, often with long-lasting effects. The fundamental issue involves contamination of nearby rivers, lakes, and aquifers by what comes out of a coal mine—usually highly acidic water containing heavy metals like arsenic, copper, and lead. The process is known as acid mine drainage .
