Abstract: To comprehensive recovery of sulphur and cobalt from Panzhihua Mining Co., Ltd. production of vanadium-titanium-iron concentrate, based on the analysis of the mineralogy technological, flotation condition test, open flow experiment and the whole process experiment by the grinding method, magnetic separation and flotation method was conducted. Experimental results show that via grinding low intensity magnetic separation-magnetism sweep-one roughing three cleaning one scavenging sulfur flotation open process, sulfur-cobalt concentrate with 56.02% Fe, 30.02% S, 0.30% Co, sulfur and cobalt recovery of 16.411% and 6.15% was obtained, Desulfurization iron concentrate with iron grade of 5569%, sulfur grade of 0.284%;Recommended industrial test process is classification grinding-low intensity magnetic separation and magnetism sweep-one roughing three cleaning one scavenging sulfur flotation closed-circuit flotation coarse.

Key words: Vanadium-titanium-iron concentrate, Magnetic separation, Sulfur float, Sulfur-cobalt concentrate, Sulfur-cobalt recovery
