Who Discovered Iron - Want to Know it
They obtained the iron from meteorites that hit the earth. Sometime between 2000 and 1200 BC the smelting of iron (that is, obtaining iron metal from iron ore) began in either India, Anatolia or Caucasus. We don't know who was the first to invent this process as artifacts containing iron are found throughout the history of these civilizations.

ORB: Iron and Steel Production in the Middle Ages
Iron is a reasonably common substance in the earth, but as any owner of an old car will attest, most of the time it takes the form of rust, iron oxide. In the smelter, iron oxides and other chemically combined forms of iron have their chemical bonds broken. This allows the iron atoms to combine into a mass of metal. Rust goes in; iron comes out.

Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.
