Method for recovering calcium from steelmaking slag |
| abstract |
The purpose of the present invention is to provide a method for recovering calcium from steelmaking slag in which it is possible, by a simpler method, to precipitate calcium eluted from steelmaking slag into a CO 2 aqueous solution. To achieve the above purpose, the present invention pertains to a method for recovering calcium from steelmaking slag. The method has: a step for bringing steelmaking slag into contact with a CO 2 aqueous solution, which is an aqueous solution containing carbon dioxide; and a step for spraying the CO 2 aqueous solution with which the steelmaking slag has been brought into contact. |
