Thermal Behavior of Pyrite and Its Relation to Carbon and Sulfur Oxidation in Clays

Thermal Behavior of Pyrite and Its Relation to Carbon and Sulfur Oxidation in Clays

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 comple...

Zusammenfassung: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.
