In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, Fe.If the reduction temperature is lower than 570 C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to Fe.The intermediate oxide, w stite Fe (1−x) O, is not stable at temperatures lower than 570 C. At reduction temperatures higher than 570 C ...

What Is Iron Ore? (With Pictures) - Info Bloom

Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or siderite. Economically viable forms of ore contain between 25% and 60% iron.
