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

WMAN » Environmental Impacts of Mining

Mining unearths large amounts of ore that contains precious metals, such as gold and silver, as well as iron and other sulfides. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams, rivers, and groundwater. This seepage is called acid mine drainage.

Box A: The Effects of Changes in Iron Ore Prices

While the iron ore price was expected to decline as additional supply came on line, the size of the fall has been larger than most forecasters anticipated. This reflects largerthanexpected increases in lowercost supply over the past few years and, more recently, a smallerthanexpected reduction in supply from highercost producers and some unexpected slowing in the growth of Chinese demand.

Environmental Risks of Mining

Deforestation due to mining leads to the disintegration of biomes and contributes to the effects of erosion. In situ leach (ISL) 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).

Strip Mining an overview | ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004. Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
