    Types of iron ore Hematite. Hematite gets its name from the Greek word for blood, haima, because of its reddish color. This is one of the types of iron ore that has very high iron content, and although the iron content of hematite itself is lower than that of magnetite, the mineral sometimes occurs in higher grade deposits, often referred to as direct shipping ore (DSO).

  • Iron Forge in Colonial America by Harry Schenawolf

    Since it melts at a lower temperature than the iron in the ore, it helps facilitate the flow of silicates and other impurities from the ore. The glassy flux also coats the iron as it melts. It forms a protective barrier between the liquid iron and the oxygen in the furnace gasses, preventing the iron from oxidizing away.
