Pollution From Mining - TheWorldCounts

1993-4-10  But mining can be extremely polluting as in the case of the "Iron Mountain" mine that will continue polluting its surrounding for 3000 years. World record in acidity: Acid drainage. The water pollution is caused by acid that drains from the “Iron Mountain” mine, known as acid drainage. Acid drainage is serious stuff.

Pollution from Mining - University of Illinois Urbana ...

2009-7-4  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.
