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.

Mining National Geographic Society
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
