Impacts of Mining on Rivers, cont. cont. from page 1 deposits can contaminate the surrounding watershed when weathering of exposed minerals causes acid drainage and metalsenriched waters. According to the EPA, mine waste has contaminated more than 40 percent of the headwaters of western watersheds. Other hardrock mines produce gypsum ...
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.
Aug 15, 2008· This study has demonstrated the contrasting effects of ironore mining and processing on metal release, speciation, and bioavailability in an impacted tropical coastal lagoon. On one hand, ironore mining and processing constitute potential sources of metals to the lagoon, on the other hand they also contribute to reducing metal bioavailability.

Mine drainage is metalrich water formed from a chemical reaction between water and rocks containing sulfurbearing minerals. Problems that can be associated with mine drainage include contaminated drinking water, disrupted growth and reproduction of aquatic plants and animals, and the corroding effects of the acid on parts of infrastructures such as bridges.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
