We studied the oxidation equilibrium of the reactions 3FeS+10CO_2&rlarr;Fe_3O_4+3SO_2+10CO MnS+3CO_2&rlarr;MnO+SO_2+3CO at 690&acd;890℃ and 600&acd;1000℃ respectively, by following method. Obtained the following equations for each reaction. Log K_<FeS>=Log p^<10>CO・P^3so_2/p^<10>CO_2=-52, 669.7/T+22.43 Log K_<MnS>=Log p^3CO・PSO_2/p^3CO_2=-18, 290.6/T+8.28 From this result calculated the equilibrium constant of the following reactions FeS+3CO_2&rlhar;FeO+SO_2+3CO FeS+2CO_2&rlarr;Fe+SO_2+2CO and obtained the following equations Log K_<FeO>=Log P^3CO・PSO_2/P^3CO_2=-18, 112.6/T+8.14 Log K_<Fe>=Log P^2CO・PSO_2/P^2CO_2=-17, 209.8/T+7.04 From these results obtained the equilibrium diagram between pco/pco_2 and pso_2 over ferrous sulphide.
