Acid Mine Drainage Overview Acid rock drainage (ARD) is produced by the oxidation of sulfide minerals, chiefly iron pyrite or iron disulfide (FeS2). This is a natural chemical reaction which can proceed when minerals are exposed to air and water.

An Explanation of Acid Mine Drainage - thoughtco.com

In a nutshell, acid mine drainage is a form of water pollution that happens when rain, runoff, or streams come in contact with rock that is rich in sulfur. As a result, the water becomes very acidic and damages downstream aquatic ecosystems. In some regions, it is the most common form of stream and river pollution.Sulfur-bearing rock, especially one type of mineral called pyrite, is routinely ...

Acid Mine Drainage - an overview | ScienceDirect Topics

Mine-acid drainage (MAD) is the run-off produced when water comes into contact with exposed rocks containing sulfur-bearing minerals that react with water and air to form sulfuric acid, dissolved Fe and Al, and other chemical elements (Blowes et al., 2004).

The study describes a new way of treating of acid mine drainage (AMD) waters containing sulphate of Fe+3 and Al+3 as dominant components using homogenous thermal hydrolysis with urea. The model solution and the acid mine drainage solution were kept with urea at one of the selected temperatures (60°C, 80°C and 95°C) in thermostatic bath.

Leadville Mine Drainage Tunnel and Treatment Plant Information

The Leadville Mine Drainage Tunnel, or "LMDT," was purchased by the Bureau of Reclamation from the Bureau of Mines in 1959. Originally, the Tunnel was a potential source of water for the Fryingpan-Arkansas Project. However, poor water quality required that the water be treated before it could be released to the Arkansas River.

Acid Mine Drainage - an overview | ScienceDirect Topics

Although acid mine drainage is the most common impact of mining on water quality, the variety of mineral geology is such that there is no single-characteristic mine water. The term "mine-impacted water" is used because it is more inclusive than terms such as acid mine drainage (AMD) or acid rock drainage (ARD).
