How is Iron Refined from Ore? (with pictures)

Mar 21, 2020 · Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
