blast furnace mineral

Steel manufacture - SteelConstruction

The blast fans the heat in the furnace to white-hot intensity, and the iron in the ore and sinter is melted out to form a pool of molten metal in the bottom, or hearth, of the furnace. The limestone combines with impurities and molten rock from the iron ore and sinter, forming a liquid '' slag '' which, being lighter than the metal, floats on ...

Iron and steel industry in India - Wikipedia

Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and marketed as pig iron ; the rest flows into basic oxygen furnaces, where it is converted into steel.
