Iron itself is found in one of the following forms: magnetite (Fe304), hematite (Fe203), goethite (FeO (OH)), limonite (FeO (OH).n (H20)), or siderite (FeC03). Pig iron, one of the necessary raw materials in making steel, is comprised partially of iron ore. Approximately 98 percent of the iron ore mined is used to make steel.
