Acid mine, drainage (AMD) is produced when sul-phide minerals, such as pyrite, found in associa-tion with the coal or overburden come into contact with oxygen and water during mining. Sulphide minerals undergo bacterially catalysed oxidation reactions which generate acidity and in-creases Fe and sulphate concentrations in recipi-ent water bodies.
