Abstract: Rod media which is widely used in high gradient high intensity magnetic separator owns features of high gradient magnetic field and large surface adsorption in separation. The teetch plate has characteristics of high intensity magnetic induction and high gradient magnetic cusps field. A new kind of profiled assembled magnetic media is designed. Contrastive experimental researches between the rod media and the profiled media with equal gap same wire diameter and equal gap different wire diameter are carried out. The results show that compared with the rod media，the profiled media is more benefit to recovery of fine iron minerals. Also，it can decline the lower limit of particle size suitable for target minerals.
