Iron Ore Processing, General
Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.
