  • How Is Iron Extracted From the Earth?

    3/26/2020· 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.

  • Iron Ore: Sedimentary Rock - Pictures, Definition & More

    How Does Iron Ore Form? Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.

  • Iron Ore Smelting Process - Bright Hub Engineering

    The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being

  • Iron ore | BHP

    It takes around 1.6 tons of iron ore to produce one ton of steel. The chemical symbol for iron is 'Fe' because of its Latin name Ferrum. We use 20 times more iron (in the form of steel) than all other metals put together. Our iron ore trains are over 2.5km (264 ore cars) long, meaning it can take half an hour from one end to the other.
