Abstract

Mg(HCO₃)₂ solution obtained by pressure carbonation of hydrated MgO was decomposed by heating to form MgCO₃ of high purity. Factors which influence the precipitation of MgCO₃, such as temperature, concentration, seeding, aeration and stirring, have been studied. Results of tests carried out with A.R. grade MgCl₂ and Na₂CO₃ at various temperatures are reported. The activation energies calculated from the rate equations are 63-85 kJ mol^-1, which suggests a chemically controlled reaction mechanism.
