  • Iron Ore

    Hematite is named from the Greek word for blood, haima, because of its reddish colour. The ore 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).
