Previous research on pyrite reactivity focused on oxidation in the laboratory [e.g., (21–23)] or in acid mine drainage (24, 25). In acid mine drainage, the rate-limiting step is oxidation of aqueous Fe(II) to Fe(III) because Fe(III) is a more efficient oxidant than O 2 in acidic conditions ( 21, 22, 24 ).
