An Explanation of Acid Mine Drainage - ThoughtCo

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 .

The pyrite is then processed to remove the iron, which is sold for a profit. The sulfur-bearing waste material that's left behind after the iron is taken out is then just discarded or piled up on the ground. Before mining, the sulfide materials naturally in the ground pose little threat to the environment. But after mining, the sulfur

The Pennsylvanian coals in the UK were deposited in a low-lying delta plain which was periodically inundated by the sea. This resulted in high S contents, mainly due to early diagenetic pyrite. Based on a statistical analysis of the geochemical data, pyrite is the major host for As, Se, Hg, Tl and Pb and an important host for Mo, Cd, Ni, Sb and Cu.

Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.
