Summary:PURPOSE: A manufacturing method of calcium carbonate is provided to increase profitability of a calcium carbonate manufacturing process by using ammonia water instead of NaOH. CONSTITUTION: A manufacturing method of calcium carbonate comprises the following steps: eluting calcium ion by placing carbonic acid raw materials(3) inside an elution reactor(2) which contains eluate(1); Inflowing the supernatant(4) in which the calcium ion is eluted after filtration; and manufacturing calcium carbonate(9) by manufacturing carbon dioxide(6) and ammonia solution(10) through a carbon dioxide scavenge process and injecting the carbon dioxide and ammonia solution into the carbonation reactor.
