The dephosphorization slag containing phosphorus in the slag, such as reduction treatment with carbon, Si, Al, such as the reducing agent, and that the first process for recovering a reducing and a phosphorus-containing molten iron to the iron oxide and the oxide in the slag, iron oxide and phosphorus oxide is used for the removed slag as the CaO source in the sintering process and containing, phosphorus-containing molten iron recovered by the second step of recycling the produced sintered ore in the blast furnace and the reduction treatment, the molten iron the handling dephosphorization until in the concentration to be less than 0.1% by weight and mixed in a third step, a blast furnace molten iron to the phosphorus-containing molten iron is in a concentration of not more than 0.1 mass% as Cheorwon to concentrated in the CaO-based flux 4 by having the process, with also a low cost and recovery of iron from the steel-making slag, that the number of the iron, and can each be utilized effectively as a resource, the steelmaking slag It provides a method for recovering iron and phosphorus from.
