Abstract: PURPOSE: A manufacturing method of lithium carbonate is provided to extract lithium carbonate from salty water which contains low concentration of lithium by carbonizing salty water in which lithium is concentrated in a specific range. CONSTITUTION: A manufacturing method of lithium carbonate comprises the following steps: providing salty water which impurity is removed(s10); concentrating lithium in the salty water by vacuum evaporating the salty water(s20); carbonizing the salty water(s30); and washing carbonate crystal(s40). A manufacturing method of lithium carbonate additionally includes a step of filtering and drying the washed lithium carbonate. Magnesium, sulfate ion, boron, and calcium are removed from the salty water. In the lithium concentration step, the vacuum evaporation is accomplished by multi-stages.
