  • How does mine drainage occur USGS

    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
