Ferric iron must first be reduced to the ferrous form before it is absorbed. Iron Recycling On a daily basis, only a small fraction of total iron requirement is gained from the diet.

WebOn Earth, iron exists in one of two oxidation states: reduced ferrous iron, depicted as Fe(II) or Fe 2+, or oxidized ferric iron, depicted as Fe(III) or Fe 3+). Sponge iron is not useful by itself, but can be processed to create wrought iron or steel. The sponge is removed from the furnace, called a bloomery, and repeatedly beaten with heavy hammers and folded over to remove the slag, oxidize any carbon or carbide, and weld the iron together. This treatment usually creates wrought iron with about three percent slag and a fraction of a percent of other impurities. Further treatment may add controlled amounts of carbon, allowi…
