An investigation on thermal behavior of Shahreza dolomite ORE

Thermal behavior of the Shahreza dolomite ore is investigated in this paper. The hydration of the calcined dolomite was studied as a function of the calcination temperature. The DTA results exhibit three endothermic peaks at 800, 900 and 1050 °C, corresponding to decomposition of MgCO3 and CaCO3, both are present in dolomite and free calcite, respectively. The results also indicated that the de...
