| titleOfInvention | Method for eluting calcium from steelmaking slag, method for recovering calcium from steelmaking slag, and device for extracting calcium from steelmaking slag |
| abstract | An object of the present invention is to provide a method for extracting calcium from a steelmaking slag by easily extracting a larger amount of calcium from a steelmaking slag into an aqueous solution containing carbon dioxide. The present invention to achieve the stated object relates to a method for extracting calcium from steelmaking slag. In the present invention, the stirring of the slurry containing the steelmaking slag in the upper-side region near the liquid surface inside the crushing / settling tank is suppressed and the steelmaking slag is settled. In the bottom region, the steelmaking slag contained in the slurry is pulverized or the surface of the steelmaking slag is pulverized. In addition, carbon dioxide is introduced into the slurry, and the pulverized or ground steelmaking slag is brought into contact with an aqueous solution in which the carbon dioxide is dissolved. |
