The thermal behavior of pyrite in air was studied. A one‐step mechanism for the oxidation of pyrite to hematite exists and accounts for previously reported weight‐loss, DTA, and gas train data which implied a two‐step mechanism. Proper control of the oxidation temperature is very important in completing the pyrite oxidation.
