Acid mine drainage from coal mining in the United States ...

Acid mine drainage (AMD) continues to be a concern in coal mining because it reduces surface water and groundwater quality (Verburg et al., 2009) and may perhaps persist for several years. In the U.S. only, AMD pollutes over 20,000 km of streams (Skousen et al., 2019). Blasting and dewatering exposes sulfide minerals, posing threats to environment.

Acid mine drainage (AMD) results from the microbiological oxidation of the sulfide residues (largely pyrite FeS 2) which remain after primary processing of sulfidic metal ores. This biological process initially yields sulfuric acid and iron in the 2+ oxidation state (Fe 2+), along with solubilization of other metals from the ore body. Subsequent chemical processes lead to the atmospheric ...
