WhatsAppعرض المزيدThe 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 .
