Which statement about iron ore and refining is accurate?

• A. False
• B. True
• C. It is not related
• D. Sometimes true

Answer: (B)

Iron ore must be refined to become usable iron. Ore contains iron tied up in minerals, usually as iron oxide, and refining (smelting and related processes) uses high heat, a reducing agent like coke, and fluxes to separate the iron from oxygen and impurities. The result is molten iron (and later steel) that can be shaped into products. So the statement linking iron ore and refining is accurate because refining is exactly the step that turns ore into metal. Saying there’s no relation or that it’s only sometimes true would miss the standard metallurgical process used to produce iron and steel.
