PURPOSE: A carbonation processing method and an apparatus are provided to manage pH of a recycled aggregate by carbonating the recycled aggregate with carbon dioxide by using a silo storing method which has a high treating efficient compared to a conventional technique. CONSTITUTION: A carbonation processing method comprises the following steps. The carbon dioxide gas is flowed in into the conical shape aggregate exhausting part(110) of the discrete chamber where the carbon dioxide gas supplied through the carbon dioxide gas supply tube(111) is positioned in the top in the state where the recycled aggregate is put into the discrete chamber positioned in the top of the multistage structured perpendicularity storage chamber(10). After the recycled aggregate filled with within the discrete chamber is contacted with the carbon dioxide gas and it is made carbonic acid with the first it is ejected to the infra positioned discrete chamber while the carbon dioxide gas rises from the lower part of the multi-stage perpendicularity storage chamber to top. The recycled aggregate again contacts with the carbon dioxide gas supplied through the conical shape aggregate exhausting part and the recycled aggregate put into the downside discrete chamber is additionally made carbonic acid, and thus pH is degraded. The carbon dioxide gas after contacting the recycled aggregate is discharged through the carbon dioxide gas discharge pipe(121) and it is collected to the collecting gas tub(21) to circulate through the carbon dioxide gas supply tube.
