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 sulfurcontaining materials in the presence of water leads to highly acidic solutions.
