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 SO42- from samples with and without coating treatment. Each sample, original or coated by TETA, was exposed to oxygen, 1×10 −3 M FeCl 3 , and Acidithiobacillus ferrooxidans, respectively,...
Pyrite samples were analyzed from two distinct locales with the intent of determining the extent of oxidative inhibition occurring in the presence of a passivating agent. Each sample was exposed to air and 9% H 2 O 2 as oxidizing agents over specific time periods with and without the presence of an iron oxide layer on the pyritic surface. The samples were submitted to passivating...
