How does mine drainage occur? - USGS

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

the acid problem has no doubt existed for much longer. In the early 1980's, the State of Montana's Department of State Lands (DSL) began to investigate possible solutions to the acid mine drainage problem. Westech/Hydrometrics (1982) inventoried the acid mine discharge points. The Montana

Acid Mine Drainage - an overview | ScienceDirect Topics

Acid mine drainage (AMD) Acid mine drainage (AMD) is the runoff produced when water comes in contact with exposed rocks containing sulfur-bearing minerals that react with water and air to form sulfuric acid and dissolved iron. This acidic run-off dissolves heavy metals including copper, lead, and mercury which pollute ground and surface 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.
