# Many everyday items are made from iron. Haematite is an ore of an iron. Haematite contains iron oxide, Fe_2O_3. What is the meaning of the term ore?

And the train bears a huge tonnage of iron ore, which contains a very high percentage of $F {e}_{2} {O}_{3}$. Before the ore is converted to metal it has to be shipped, prepared, and then shunted to a blast furnace............All of this is highly energy intensive.
