How Was Iron Extracted in Ancient Times?
The first evidence of iron use dates back to around 3000 BCE in Anatolia (modern-day Turkey). During this period, iron was used primarily for decorative purposes and was made by heating iron ore in a fire and then hammering it into shape. This method is known as 'wrought iron' and was used extensively throughout the first Iron Age.

Ironmaking 101 – From Ore to Iron with Blast Furnaces
Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...
