PURPOSE: A manufacturing method of a sintered dolomite is provided to easily separate and remove impurities in a magnesium heat-reduction process by screening the rotation rate of rotary kiln furnace in a discharging process. CONSTITUTION: A manufacturing method of a sintered dolomite comprises a step of injecting dolomite mineral into a heating kiln furnace; a step of heating the heating kiln furnace while rotating; a step of moving the dolomite mineral to a cooling kiln furnace and cooling the cooling kiln furnace while rotating the same; and a step of filtering the dolomite mineral with a sieve. The temperature of the heating kiln furnace is 850-1350°C. The size of the sieve is 4mm or less. The content of the SiO2 is 1 wt% or less. The rotation rate of the kiln furnaces vary with the size and the length of the furnace and the kinds of the mineral.
