  • Iron Ore Mining | Techniques | Metal Extraction

    Iron is concentrated by the process of calcinations Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top It is in the blast furnace that extraction of ironIron Mining Process From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation’s steel Blasting Taconite is a very hard rock Using explosives, the taconite is blasted into small pieces The iron oreIron Mining Process Minnesota Iron
