Iron Ores | Article about Iron Ores by The Free Dictionary

The iron content of industrial ores varies within wide limits, from 16 to 70 percent. A distinction is made among rich ores (≥ 50 percent iron), ordinary ores (50–25 percent iron), and poor ores (≤ 25 percent iron). Depending on their chemical composition, iron ores are used to make pig iron after dressing or in their natural state.
