  • Why Magnetite Ore Not Use In Blast Furnace

    The blast furnace After the crushing process, the iron ore was ready for the blast furnace. The 16-meter high blast furnace stack was loaded from the top with alternating layers of iron ore and coal. The furnace master was in charge of operating the furnace and making sure the raw materials were added correctly. Iron ore from different mines.Ferro-coke, as a new burden of blast furnace (BF), can not only greatly reduce the energy consumption and CO2 emission, but also promote the resource utilization by using the low-quality iron ore and low-grade coal. However, the strength of ferro-coke decreased with the increasing amount of iron ore powder. In order to maintain the strength of ferro-coke while increasing the amount of iron ore.

  • Mining Technology: Iron Ore Processing For The Blast Furnace

    Santanu Chakraborty, in Treatise on Process Metallurgy Industrial Processes, 2014. 5.3.7 Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.The charge is added to the top of the blast furnace, and hot air is blasted in through the bottom. The oxygen in the air reacts with the coke in the charge to form carbon monoxide. The carbon monoxide in the blast furnace reduces the iron(III) oxide in the hematite ore to produce molten iron. Iron ores contain a large amount of sandy impurities.
