On the other hand, the iron ore used in this study has a density of 3705 kg/m 3. Therefore, if the same size of the fine was produced, the iron ore was a heavier fine, eventually leading to a larger K c. The other reason is that catalysts are mainly made as mentioned in chap 3.2, while iron ores are particles that come from the nature.
