  • What Is Iron Smelting? (with pictures) - wiseGEEK

    2020-5-30  Iron smelting is an industrial process used to extract usable iron from raw ore with the use of heat and chemical agents. After smelting, the iron can be further processed and alloyed with other materials to produce a wide range of metal products. These products can be used for everything from cooking utensils to the development of structural steel. ...

  • smelting Definition Facts Britannica

    In the smelting process a metal that is combined with oxygen—for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping as carbon monoxide or carbon dioxide. Other impurities, collectively called gangue, are removed by adding a flux with which they combine to form a slag.

    2020-6-30  Smelting is the general term for getting a metal from its natural ore.Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.

  • An Introduction to Iron Smelting – Part I: Theory –

    The Basic MechanicsOreFuelThe FurnaceIron SteelAfter The Smelt – Processing The BloomA Conclusion to Part IThe smelting, or reduction, of iron ore is a thermochemical reaction, wherein the iron oxides are reduced to metallic iron. Impurities in the ore are melted out of the ore in the form of slags – most commonly iron silicates – while the iron itself is never truly molten. Instead the product of the smelt is a spongy mass of iron and slag known as a ‘bloom’. This then needs to be consolidated by hammering while the bloom is at a (white) welding heat. In doing so, the slags trapped in the bloom a...

  • How iron is made - material, manufacture, making,

    The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.
