Conflicted Over Copper: How the Mining Industry Developed ...

 · The iron ore mines continued operating throughout the 20th century, but the issue of pollution didn''t come to a head until the 1970s. At that point, taconite mines had been running for years, and Minnesota believed the waste material—tailings—couldn''t hurt the environment.

How can mining become more environmentally sustainable ...

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 ...

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.

Mining | Water for all

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
