摘　　要：在查明攀西地区某钒钛磁铁矿多元素分析和目的矿物成分的基础上,针对该矿石的选铁尾矿进行了磁选、重选、电选、浮选工艺研究,揭示了各工艺对不同脉石矿物的去除规律。在此基础上,确定了两种工艺流程,采用粗粒电选-细粒浮选流程,可获得精矿钛品位47.11%、回收率22.17%的指标;采用强磁精全浮流程,可获得精矿钛品位47.05%、回收率22.08%的指标。Based on multi-element analysis and targeted mineral composition of the vanadium-titanium magnetite in Panxi area,the titanium concentrate separation including magnetic separation,gravity separation,electric separation,and flotation process had been carried out upon the iron tailings,in order to reveal removal methods of different gangue minerals by individual process.Therefore,two technological processes had been determined.The electric separation of coarse-grained particle-flotation process of fine-grained particle can be used to obtain a titanium concentrate grade of 47.11%and a recovery of 22.17%.The high intensity magnetic separation concentrate is floated with whole flotation process,and it can obtain titanium concentrate with grade 47.05%and recovery 22.08%.
