Abstract: There are abundant deposits of magnetite associated with vanadium and titanium in Panzhihua region，Chengde region and other places in China. In the early days，ilmenite is mainly recovered by gravity separation and electric separation. TiO2 recovery can only reach about 10% and enormous fine ilmenite particles are lost in the tails. From 1994，SLon vertical ring and pulsating high gradient magnetic separators are applied into ilmenite processing industry，which can effectively recover fine ilmenite particles. The development of SLon magnetic separators and flotation technology promoted the rapid development of ilmenite processing technology in China. Nowadays，ilmenite recovery has normally reached 40%. However，there is still great potential to raise ilmenite recovery in China. Through optimizing ilmenite processing flow sheet and equipments，ilmenite recovery still can be raised to 50%~60%. If the breakthrough on beneficiation technology for -20 μm ilmenite is made to recover some of titanium ores from the high intensity magnetic separation and tailings flotation，the titanium recovery is expected to reach 70%.
