Mines and environmental impact SGU

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 metalrich leachate into the surrounding environment, known as Acid Mine Drainage (AMD).
