Method for eluting calcium from steelmaking slag, and method for collecting calcium from steelmaking slag |
abstract |
The purpose of the present invention is to provide a method for eluting Ca from steelmaking slag such that a large amount of Ca can be eluted from the steelmaking slag into an aqueous solution containing carbon dioxide. The present invention executes, in this order: a step for removing an iron-containing compound from steelmaking slag by performing magnetic separation on the steelmaking slag; and a step for bringing the steelmaking slag subjected to magnetic separation into contact with an aqueous solution containing carbon dioxide. In addition, the aqueous solution containing carbon dioxide and the steelmaking slag are brought into contact with each other while the steelmaking slag is being pulverized or the surface of the steelmaking slag is being ground. |
