Abstract
The present invention provides a method for carbon dioxide fixation, which comprises extracting an alkali metal component from a raw slag in a first reactor by using an ammonium salt solvent to produce a solution containing the extracted alkali metal component and then reacting the solution with carbon dioxide in a second reactor to produce a carbonate precipitate. With this method, an alkali metal component can be extracted and a carbonate precipitate can be obtained in a simpler and cost-effective manner, among others.
