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.
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 ...
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).
reclamation. The problem of acid mine drainage has been widely known for many years and it was the main reason the federal government enacted the Surface Mining Control and Reclamation Act in 1977 to regulate the coal mining industry. Since enactment of that law, a great deal of experience has
Acid Mine Drainage Remediation . In Colorado alone there are over 30,000 abandoned mines. Heavy metals emanating from former mine sites are a major threat to water resources. Sulfate-reducing bacteria (SRB) present a natural way to reverse the damage caused by acid mine drainage.
This research project is directed towards the development of an automated, solar-powered, flow-through prototype system for the continuous unattended treatment of acid mine drainage (AMD), which can be found at thousands of abandoned mines.

Acid mine drainage is a problem at a number of active Alaskan metal mines including Red Dog, Greens Creek, and Kensington Mine. The potential impacts of acid mine drainage on Bristol Bay fisheries is the primary source of opposition to the proposed Pebble Mine in southwestern Alaska and also a concern at the proposed Donlin Gold Mine.

OVERVIEW OF ACID MINE DRAINAGE TREATMENT WITH CHEMICALS Jeff Skousen West ia University ACID MINE DRAINAGE FORMATION Acid mine drainage (AMD) forms when sulfide minerals in rocks are exposed to oxidizing conditions in coal and metal mining, highway construction, and other large-scale excavations.
Acid mine drainage (AMD) is recognized as one of the most serious environmental problem in the mining industry. The problem of acid mine drainage (AMD) has been present since mining activity began thousands of years ago. This paper describes the water pollution issues in mining industries and their treatment technologies.
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.
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, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...

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).
