ABSTRACT The current beneficiation study examines the potential for separating ultrafine low-grade iron ore materials using a circulating-type air classifier. Statistical analysis using Response Surface Methodology (RSM) was implemented for optimization of the separator critical processing parameters to achieve sharp separation at a cut size as fine as 20–38 µm.
