Abstract: Grinding products with particle size of -0.038 mm(usually being called ultra fine ilmenite) are usually discarded as slimes in titanium concentrator in Western Panzhihua area.To more efficiently utilize the resource，beneficiation experiments were conducted on the deslimed products in this region with particle size of 95% -0.038 mm，TiO₂ content 8.80%，and harmful element sulfur content 0.62%.The results showed that：through pre-concentration of one roughing，middlings reprocessing by gravity separation using suspension vibration cone separator，desulfurating by one-stage flotation on the gravity concentrate，and titanium concentration by one roughing，three cleaning，one scavenging and middlings back to the flowsheet in turn process to deal with desulfurated products，titanium concentrate with TiO₂ grade of 47.01% and the recovery rate of 28.58% were obtained.Therefore，the process of gravity separation by the hanging vibration cone concentrator-flotation can realize the efficient recovery of ultra fine ilmenite.
