In　order　to　reveal　the　difference　of　several　thermal　analysis　methods　for　calculating　the　kinetic　parameters　of　the　oxidation　reaction　of　sulfide　ores,　thermal　analysis　experiment　was　carried　out　on　a　sample　from　typical　sulfur-rich　mine　by　using　STA449C　thermal　analyzer.　Integration　methods　such　as　Coats-Redfern,　Doyle,　Flynn-Wall-Ozawa　(FWO)　and　differentiation　methods　such　as　Kissinger,　Fridman　and　Achar　were　used　to　calculate　the　dynamic　reaction　parameters　of　oxidation　decomposition　of　sulfide　ore　samples.　The　results　show　that　the　oxidation　process　of　sulfide　ores　is　in　accordance　with　the　first　order　reaction　kinetics　mechanism.　The　kinetic　parameter　values　of　sulfide　ore　samples　at　the　high　temperature　stage　are　significantly　higher　than　those　at　low　temperature.　By　comparison　of　the　results　of　different　thermal　analysis　methods,　it　can　be　concluded　that　the　results　obtained　by　the　different　methods　can　all　show　combustion　diversities　of　oxidation　reaction　of　sulfide　ores,　but　the　discrepancy　among　results　is　remarkable　depending　on　the　specific　method　of　calculation　used.　Therefore,　the　FWO　method　is　used　to　check　the　kinetic　parameters　of　the　oxidation　and　decomposition　process　of　sulfide　ores　by　using　the　method　of　Coats-Redfern　or　Doyle　by　thermal　analysis　method　under　appropriate　heating　rate.　©　2018,　Central　South　University　Press.　All　right　reserved.
