what is the primary metallic ore of hematite

  • Iron Ore ScienceViews

    Metallic iron, from which steel is derived, must be extracted from iron ore. Steel is a combination of iron with a small amount of carbon. When heated in the presence of a reductant, iron ore will yield metallic iron. Iron ore almost always consists of iron oxides, the primary forms of which are magnetite and hematite. Iron ore is

    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.
