A review on pyrrhotite oxidation

Journal of Geochemical Exploration, 2004
The non-stoichiometric compounds of iron sulphide named pyrrhotite (Fe1−xS) are often associated with pyrite (FeS2) in sulphidic ores and their waste products. The factors affecting pyrite and pyrrhotite oxidation are similar but the latter has received much less attention.

The passivation of pyrrhotite by surface coating

Chemosphere, 2005
The potential of triethylenetetramine (TETA) to inhibit the oxidation of three pyrrhotites, Garson, McCreedy and Po-97 has been studied systematically and confirmed by comparing the release of Fe and SO4(2-) from samples with and without coating treatment.
