Mining and Water Quality. Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing 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 ...

Iron mining in the Schefferville, Quebec, area has resulted in the disruption of some small surface drainage systems and the discharge of large amounts of pumped groundwater into them. Major ion concentrations in surface waters is controlled by the occurrence of the Denault (dolomite) formation, and little change is caused by the mining activities.

Oct 12, 2020 When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process. This weathering results in the release of an acidic and often metal-rich leachate into the surrounding environment, known as Acid Mine Drainage AMD.
