• Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

Iron ore as a main dry cargo - OpenSea

Iron Ore: The King of the Dry Bulk Shipping. The iron ore is the dry bulk cargo with the largest trading volume per year, above coal and grains. Iron ore is found in nature in form of rocks, usually mixed with other elements and after it is processed by various industrial processes, it is sold to steel companies.

Investigation on Iron Ore Grinding based on Particle Size ...

The iron ore blend takes RT of 13 min when grounded in the BBM for 250% circulating load with 80% passing particle size of 56 µm. The blend iron ore sample obtained from the BBM is composed of a higher percentage of fines and is not suitable for pellet making. So, the grinding is carried out in the LBM by varying the retention time of the mill.
