摘要:
is investigated of kinetics oxidation of Fe(II) to Fe(III) by manganese ore (100-250 % from theoretical different conditions of loading) in solution, containing 2 g/dm(3) Fe(II) and 14 g/dm(3) H2SO4 at temperature 17-18 degrees C. As the result it is established that in the summary reaction 2FeSO(4) + MnO2 + 2H(2)SO(4) = Fe-2(SO4)(3) + MnSO4 + 2H(2)O, the first stage, which limits the velocity of total process, is the interaction between MnO2 and H2SO4, giving MnSO4 and atom oxygen. This oxygen than energetically oxidates FeSO4 to Fe-2(SO4)(3).
