Abstract
Mining activities for metals or coal often result in the development of acid mine drainage
due to the oxidation of sulfidic minerals which get exposed to oxygen. The acidic mine waters are
characterized by low pH, high concentrations of sulfate and ferrous iron, and possibly dissolved
heavy metals or metalloids. Conventional treatment comprises neutralization and oxidation yielding
a sludge of iron oxides/hydroxides.
