Abstract Under high pressure and temperature pyrite is oxidized into sulfuric acid and ferric oxide in the acid solution. According to the reaction mechanism reported in the literature, the pyrite is first converted into ferrous sulfate and then is oxidized into ferric sulfate in the solution. On further reaction the ferric salt is hydrolyzed into hydroxide and then changed into ferric oxide. Kinetic studies carried out recently in our Institute indicate that the reaction product α-Fe_2O_3 is the direct oxidation product of pyrite and a new reaction mechanism was proposed. Radioactive Fe~(55,59) was used in this study as tracer to study the reaction mechanism. Results are in agreement with the mechanism proposed recently and indicate that the one reported in the literature is incorrect.
