Environmental Impact of Steel TheWorldCounts

Environmental Impact Of Steel Theworldcounts

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 causes water pollution of heavy metals and acid that drains from the mines.

Environmental Risks of Mining

Environmental Risks Of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Mining Problems and Possible Solutions Tasmanian

Mining Problems And Possible Solutions Tasmanian

Feb 14, 2013 The overburden from an open pit mine (the worlds preferred mining method) sometimes reaches five times the mass of minerals removed for processing. Overburden is piled near the mine and can become unstable and dangerous. Some overburden mountains are as high as 200m and can be poisonous to ground water and animal life.

Pollution from Mining

Pollution From Mining

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.

How does mine drainage occur USGS

How Does Mine Drainage Occur Usgs

Mine drainage is formed when pyrite (an iron sulfide) is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage. The acid runoff further dissolves heavy metals such as copper, lead, and mercury into groundwater or
