These microbes increase the production of sulfuric acid from the surrounding rock, further poisoning the downstream environment for other organisms. This feedback loop is an important component in all the most severe cases of acid mine drainage.

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
