    Iron Ore: In sponge iron making, iron ore is reduced in solid state. Unlike in the conventional steel melting processes, the gangue content of iron ore cannot be separated as a slag. Therefore, it becomes imperative to select an ore with a high Fe content and a low gangue content, to optimize yield .

  • How is Iron Refined from Ore? (with pictures)

    To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to. Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.

  • Iron ore

    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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

  • Direct Reduced Iron (DRI)

    Directreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ...
