    2023年5月7日  Mining and processing: Iron ore is typically mined through open-pit or underground mining methods, depending on the depth and location of the deposit. After extraction, iron ore is processed to remove The majority of Earth's iron, however, exists in iron ore. Mined right out of the ground, raw ore is mix of ore proper and loose earth called gangue. The ore proper can usually be separated by crushing the raw ore and simply Iron Ore HowStuffWorksThe iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate.Iron Mining Process - Minnesota Iron
