The term ''acid rock drainage'' (ARD) is widely used for any acid drainage produced from rock, whether mined or not. There are numerous examples of natural acid rock drainage (NARD, see Nordstrom, 2015), acid drainage from mining activities or acid mine drainage (AMD), and acid drainage from other construction activities that must excavate sulfiderich rock for construction of buildings

How does mine drainage occur? USGS.gov

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

New perspectives in acid mine drainage microbiology

Acid mine drainage arises from the exposure of metal sulfide minerals, such as pyrite (FeS 2), to oxygen and water during the mining of metals and coals (Johnson, 2003). Many metals occur chiefly as sulphide ores (e.g. zinc in sphalerite), and these tend to be associated with pyrite, which is the most abundant sulphide mineral on the planet.

Mine drainage is metalrich water formed from a chemical reaction between water and rocks containing sulfurbearing minerals.

Geomicrobiology Wikipedia

Another appliion of geomicrobiology is bioleaching, the use of microbes to extract metals from mine waste. For example, sulfatereducing bacteria (SRB) produce H 2 S which precipitates metals as a metal sulfide. This process removed heavy metals from mine waste which is one of the major environmental issues associated with acid mine drainage (along with a low pH).
