  • How is iron extracted from its ore? – The Geek City – Your ...

    Iron is extracted from the ore containing the maximum amount of iron. This is found near the surface of the Earth. Iron ore is converted to iron by various processes. The most common process is the use of a blast furnace to extract pig iron. Pig iron comprises of about 92-94% iron and about 3-5% of carbon along with other impurities.
