Reclaiming Hard Rock Mines: An In Depth Look at …

Acid mine drainage (AMD) is a persistent environmental problem around the world, forming when mining activities expose sulfide minerals to the near-surface environment and oxygen-rich water.

Acid mine drainage - Wikipedia

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 ...

FACT SHEET ACID MINE DRAINAGE The Problem

FACT SHEET ACID MINE DRAINAGE The Problem The formation of acid mine drainage and the contaminants associated with it have been described as the largest environmental problem facing the U.S. mining industry.1 Acid mine drainage occurs when sulfide minerals in the waste rock react with air and water to form sulfuric acid.

ACID-BASE ACCOUNTING: AN IMPROVED METHOD OF …

Acidic mine drainage (AMD), which results from the accelerated oxidation of pyrite (FeS 2) in mined coal and overburden, has contaminated thousands of miles of streams in the Appalachian region of the United States. Acid-base accounting (ABA), which simplifies the complex hydrogeochemical system through use of a limited number of variables, commonly is used to predict the post-mining occurrence of AMD.
