    The Basic MechanicsOreFuelThe FurnaceIron amp; 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 aLive Chat
