Method for eluting calcium from steelmaking slag and method for recovering calcium from steelmaking slag |
| abstract |
To provide a method for eluting Ca from steelmaking slag, in which a large amount of Ca can be eluted from steelmaking slag into an aqueous solution containing carbon dioxide. A method of magnetically separating steelmaking slag to remove a compound containing iron from the steelmaking slag, and a step of contacting the steelmaking slag subjected to magnetic separation with an aqueous solution containing carbon dioxide in this order. Do. Moreover, the aqueous solution containing a carbon dioxide and steelmaking slag are made to contact, grind | pulverizing steelmaking slag or grinding the surface of steelmaking slag. By these methods, a large amount of Ca can be easily eluted from the steelmaking slag into an aqueous solution containing carbon dioxide. [Selection] Figure 1 |
