Discovery of Iron. The first iron used by humans is likely to have come from meteorites. In Mesopotamia (Iraq) there is evidence people were smelting iron around 5000 BC. Artifacts made of smelted iron have been found dating from about 3000 BC in Egypt and Mesopotamia.
Where is iron produced naturally?
It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space.
How do we get the element iron?
Iron is used more than any other metal for producing metal alloys. The most important iron alloys include cast iron, pig iron, wrought iron, and steel. There are various alloys of steel, but they all contain iron as the main metal. Carbon is one of the main alloying elements mixed with iron to make steel.
