About Iron Ore. Iron ore is a mineral aggregate containing iron elements or iron compounds that can be economically utilized. Any ore containing economically available iron is called iron ore. There are many kinds of iron ores. The main 4 types of iron ores are Magnetite (Fe3O4), Hematite (Fe2O3), Limonite(Fe2O3．nH2O), and Siderite
