Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called "iron ore pellets" suitable for use in an ironmaking furnace at a steel mill, such as a blast furnace or electric arc furnace. In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16 ...

Production of pellet as a desirable feedstock for ironmaking furnaces has exceeded 300 Mt per year in 2005, accounting for about 24% of the iron ore processed globally (UNCTAD, 2006). The production of iron ore pellets involves two major steps, forming the "green" pellets in rotary disks or drums, followed by their heat

Then the iron ore pellets will sent through metallic conveyor into the furnace to undergo heating process at 1200 degrees. After the heating process, the heated base mix will converted into a semi liquid cake. Using a sinter breaker machine the cake is break into small pellets. Finally these iron ore pellets under goes cooling in the cooling tower.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

• Lime kilns and coke oven plants are not included in the system boundaries for iron and steel production. This is bec ause the outputs of those plants ( lime and coke) are not CBAM goods themselves. Consequently, lime and coke are also not considered precursors for the calculation of the specific embedded emissions. •
