Abstract
The study of kinetics of Fe(II) oxidation to Fe(III) by manganese ore at the content in the initial sulfate solution of 2g/dm3 Fe(II), 14g/dm3 H2SO4 and temperature 17-18°C, oxidant consumption 100-250% of the theoretical one and different mode of its loading was established, that in the total reaction 2FeSO4+MnO2+2H2SO4=Fe2(SO4)3+MnSO4+2H2O the first stage limiting the speed of the whole process is the interaction of MnO2 with sulfuric acid with the formation of MnSO4 passing into solution and active (atomic) oxygen, oxidizing then vigorously FeSO4 to Fe2(SO4)3.
