large capacity slag iron ores

Iron ores contain a large amount of sandy impurities. These impurities are removed from the blast furnace when they react with calcium oxide compounds. Molten iron and molten slag accumulate at the bottom of the blast furnace, while waste gases, such as carbon dioxide and nitrogen, escape through pipes at the top of the blast furnace.
