  • Iron processing - Ores | Britannica

    Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.

  • How Is Iron Extracted From the Earth? | Reference

    Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

  • Direct reduced iron - Wikipedia

    The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.


    Currently beneficiation of hematite ores is conducted using either direct flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-
