What Are the Different Uses of Iron Ore? (with pictures)

May 22, 2019· Steel production consumes the vast majority of iron ore produced around the world. To make steel, firms start by crushing and pre-processing ore before smelting it to free the trapped metal with a heat and chemical reaction. This can be used to make so-called “pig iron,” solid blocks of iron that can be further processed.

How is Iron Refined from Ore? (with pictures) - wisegeek.com

Jun 19, 2019· 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.
