Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (5560%)rich ore is usually used.

Iron ores such as hematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
WhatsApp: +86 18838072829How Iron Was Made. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s waterpowered hammers ...
