摘要： The purpose of the present invention is to provide a method for recovering calcium-containing solid components from steelmaking slag, with which it is possible to easily increase the calcium recovery rate. With the method, steelmaking slag is immersed in an aqueous solution containing carbon dioxide, and calcium in the steelmaking slag is made to leach out into the aqueous solution. Next, the immersed steelmaking slag is removed from the aqueous solution, and, subsequently, the pH of the aqueous solution is increased. When solid components precipitated by doing so are recovered, it is possible to recover solid components containing 20 % or more by mass in terms of calcium atoms.

摘要： The invention provides a method for recovering (collecting) iron and phosphorus from steelmaking slag, which includes a first step in which phosphorus-containing steelmaking slag such as dephosphorization slag is reduced using a reducing agent containing for example carbon, Si or Al to reduce iron oxide and phosphorus oxide in the slag and to recover them as phosphorus-containing molten iron, a second step in which the steelmaking slag from which the iron oxide and the phosphorus oxide have been removed is used as a CaO source in a sintering step and the resultant sintered ore is recycled to a blast furnace, a third step in which the phosphorus-containing molten iron recovered by the reduction is dephosphorized to a phosphorus concentration in the phosphorus-containing molten iron of not more than 0.1% by mass, thereby phosphorus being concentrated in a CaO-containing flux, and a fourth step in which the phosphorus-containing molten iron dephosphorized to a phosphorus concentration of not more than 0.1% by mass is mixed as an iron source with a blast furnace hot metal. The method thus enables inexpensive recovery of phosphorus and iron from the steelmaking slag, and the phosphorus and the iron recovered are effectively used as resources.
