IRON SOURCE PRODUCTION METHOD

To provide a method for producing an iron source capable of sufficiently removing phosphorus even when phosphorus existing in iron ore is bonded to iron.SOLUTION: A method for producing an iron source comprises: a preparation step of preparing a composition for roasting containing iron ore having 0.05 mass% or more of phosphorus, where the total amount of Al2O3 and SiO2 is 5.0 mass% or more when the elements contained in the composition for roasting are converted into oxides; a roasting step of obtaining a roasted product by roasting the composition for roasting; a reduction step of obtaining a reduced product containing a reduced iron phase and a slag phase by reducing the roasted product in an atmosphere containing at least one of CO gas and hydrogen gas; a grinding step of obtaining a pulverized product containing a reduced iron phase-containing product in which at least a part of the slag phase constituting the reduced product is separated by pulverizing the reduced product; and a sorting and recovering step of sorting and recovering the reduced iron phase-containing product from the pulverized product.SELECTED DRAWING: Figure 1 【課題】鉄鉱石中に存在するリンが鉄と結合している場合であっても、リンを十分に除去できる、鉄源の製造方法を提供する。【解決手段】リンを０．０５質量％以上含有する鉄鉱石を含む、焙焼用組成物であって、前記焙焼用組成物に含まれる元素を酸化物換算したときの、Ａｌ２Ｏ３とＳｉＯ２の合計量が５．０質量％以上である焙焼用組成物を、準備する準備工程と、前記焙焼用組成物を焙焼して焙焼物を得る焙焼工程と、前記焙焼物を、ＣＯガスと水素ガスの少なくとも１つを含む雰囲気で還元して、還元鉄相とスラグ相を含む還元物を得る還元工程と、前記還元物を粉砕して、還元物を構成するスラグ相の少なくとも一部が分離した還元鉄相含有物を含む、粉砕物を得る粉砕工程と、前記粉砕物から前記還元鉄相含有物を選別回収する選別回収工程とを含む、鉄源の製造方法。【選択図】図１
