In many impoundments a variety of sulfide minerals is present. Jambor 1994 reported a general sequence of sulfide-mineral reactivity observed in several impoundments, from the most readily attacked to the most resistant, to be pyrrhotite→galena-sphalerite→pyrite-arsenopyrite→chalcopyrite→magnetite. Blowes and Jambor 1990 observed systematic variations in
