The non-isothermal kinetics of decomposition of manganese carbonate ore from Denizli Tavas region was studied. The ore decomposed according to a serie of reaction, MnCO3 →(400-600°C) MnO2 →(>600) Mn2O3. By using of Kissenger equation, the activation energies for the decomposition of MnCO3 to MnO2 and the transformation of MnO2 to Mn2O3 were calculated as 185,7 kJ/mol and 217,3 kJ/mol, respectively.
