In this study, the fine generation ratio of the iron ore was determined in a cyclone. The importance of the sifting effect on the iron ore is greater than that on catalyst particles because the iron ore has a shorter residence time. For this reason, the effect of the sifting effect was determined by calculating r spd over time.
