Map of impact by acid mine drainage in the river network

May 01, 2018· The Iberian Pyrite Belt (IPB), in the southwest of Europe, is characterized by high levels of contamination by acid mine drainage (AMD) in a large extent of its river network. In this scenario, it is necessary to characterize the degree of pollution of the mining leachates in the AMD-generating sources as well as of the main receiving watercourses.

How does mine drainage occur? USGS

Mine drainage is formed when pyrite (an iron sulfide) is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage. The acid runoff further dissolves heavy metals such as copper, lead, and mercury into groundwater or

Mine Waste Transfer and Disposal Methods Mine Tailings

Acid mine drainage is a heavy contributor to pollution of surface water across the globe. AMD is primarily caused when water flows over the sulfide-heavy material, forming an acidic solution. Water at mine sites is usually heavily monitored and management strategies are used to not only reduce the amount of mine water produced but also to treat
