The passivation of pyrrhotite by surface coating.


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. Each sample, original or coated by TETA, was exposed to oxygen, 1 x 10(-3) M FeCl3, and… (More)
