Conclusions The rate of decarbonization in magnesite critically depends on the grain size. With an increase in the grain size the process rate diminishes, especially when we change from particles measuring less than 10 mm to particles measuring 30 mm. The retardation in the decarbonization rate is due to the slower heating of the large fractions of magnesite, the formation of low conducting layers, hindering access of heat to the center of the grains, and the enhanced concentration of CO2 in the gas phase. The relationship between the time for complete decarbonization and the grain size of the magnesite is expressed by a parabolic equation, the numerical coefficients for which vary with temperature change.
