METHOD FOR ELUTING CALCIUM FROM STEEL SLAG AND METHOD FOR RECOVERING CALCIUM FROM STEEL SLAG
The purpose of the present invention is to provide a method for eluting calcium from steel slag such that more calcium can be eluted into an aqueous solution containing carbon dioxide from the steel slag. The present invention comprises carrying out, in the following order, a step of subjecting a calcium compound contained in the steel slag to hydration and a step of bringing the steel slag subjected to the hydration into contact with the aqueous solution containing carbon dioxide. Furthermore, in the present invention, the aqueous solution containing carbon dioxide is brought into contact with the steel slag while the steel slag is being pulverized or the surface of the steel slag is being ground. As a result of these methods, more calcium can be easily eluted into the aqueous solution containing carbon dioxide from the steel slag.
