Iron Discovery . Discovery Date: Ancient Times Name: Iron derives its name from the Anglo-Saxon 'iren'.The element symbol, Fe, was shortened from the Latin word 'ferrum' meaning 'firmness'. History: Ancient Egyptian iron objects have been dated to around 3500 B.C. These objects also contain approximately 8% nickel showing the iron may have originally been part of a meteorite.

Iron Ore is an early-game ore that generates upon world creation on the surface, as well as in the Underground and Cavern layers. Its primary use is in crafting Iron Bars, which can then be used to craft the Iron tier of tools, weapons, and armor, as well as Buckets, Chains, and several other items. The equivalent of Iron Ore is Lead Ore, which will sometimes replace Iron in a world. Iron Ore ...

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
