Treating Acid Mine Drainage From Abandoned Mines in …

Active treatment of mine drainage requires precipitating metal contaminants from the water and neutralizing acidity (Hedin and others 1994). Passive treatment differs from active treatment by distinguishing between these two objectives. It is possible to passively remove iron contaminants from mine water, but have little effect on the mine ...

Acid mine drainage (AMD) from mining wastes is one of the current environmental problems in the field of mining pollution that requires most action measures. This term describes the drainage generated by natural oxidation of sulfide minerals when they are exposed to the combined action of water and atmospheric oxygen.

What is Acid Mine Drainage? - Definition from Corrosionpedia

Acid mine drainage is known as one of the most severe threats to water brought about by mining. A mine's drainage substances such as acid can destroy streams, rivers and aquatic life. The effects of this phenomenon are so immense that it can cause devastation that could last for hundreds to …

What can be done to prevent or clean up acid mine drainage ...

Water flowing through active or abandoned mine sites can become polluted by the material being mined[1]. By far the most common mine drainage problem is that of acid mine drainage (AMD). Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria[1].

Environmental Mine Waste Management

prevention, control, or treatment of acid mine drainage, nor does it address the entire range of possible preventive technologies currently in use. As a result of this literature review, it was determined that there is no single, correct approach to environmental mine waste management. Successful mine waste management and mitigation

How can acid mine drainage be treated?

Treatment of AMD: Acid mine drainage sometimes forms when certain minerals in the soil and rocks around mines are exposed to weathering processes during mining.These exposed minerals release their contents into creeks causing them to become acidic. This kind of pollution damages aquatic life and makes the water useless or harmful for others who depend on it for recreation or drinking water.

Operation and Maintenance of Passive Acid Mine

Acid mine drainage (AMD) is a solution of sulfuric acid and metals that forms when mining exposes pyrite to air and water. AMD pollutes streams in many areas where coal was mined before passage of the Surface Mining Control and Reclamation Act (SMCRA, 30 U.S.C. §1201 et seq.).

Acid mine drainage - microbewiki

Acid mine drainage (AMD) occurs when metal sulfides, most commonly pyrite, are exposed to and react with air and water. When water flows over or through sulfur-bearing mine tailings, a chemical reaction occurs between the water and rocks resulting in metal-rich water.

Technical Document: Acid Mine Drainage Prediction

Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.
