What are iron ore pellets? Iron ore pellets are spheres of typically 816 mm to be used as feedstock for blast furnaces. They contain 6472% iron and additional materials, which can adjust the chemical composition and metallurgical properties of the pellets. The iron ore pelletization is the process of converting iron fines less than 200 mesh ...

Abstract 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.
