Abstract
The present invention relates to a method and system for recovering carbonate from steel slag, in which it is possible to extract carbonate from steel slag and reuse the extracted carbonate, and to recycle steel slag and make use of COgas without emission to the atmosphere. Since unreacted metal ions and an acidic solvent are reused in the method and system, it is possible to increase carbonate extraction efficiency and reduce an amount of waste.
