Stoichiometric,sulfur- and arsenic- deficient arsenopyrite have practically the same oxidation rate. Arsenopyrite is covered with a metal deficient sulfide layer which appears to determine the restpotential of the electrode. This layer can be separately oxidized and reduced during bulk-oxidation of arsenopyrite. Arsenopyrite oxidation is accelerated by dissolved Na2SO4 and by high electrode potentials and solution acidity. The rate is controlled by a surface reaction with an apparent activation energy of 33kJmol−1.Type of Medium: Electronic ResourceURL:
