Iron ore Wikipedia
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning .
