Iron-bearing materials The major iron-bearing materials are iron ores, sinter and pellet in the blast furnace. Their function is to supply the element iron, which is 93 to 94 percent of the pig iron produce. Iron ores are classed by their chemical compositions, such as oxides, sulfides, carbonates, etc, as shown in the table below. Class and mineralogical name Chemical composit
