摘要
攀枝花某铁尾矿中钛主要以钛铁矿、钛磁铁矿形式存在,由于原生产工艺不合理导致钛精矿中钛回收率低、硫品位高等问题,为此进行了详细的选矿试验研究。经多方案对比,最终确定采用弱磁选—强磁选—螺旋溜槽重选—电选工艺,可获得TiO_2含量47.33%、回收率为55.13%、含硫0.15%的钛精矿,为后续的工艺流程设计提供了依据。
mThe dominant titanium bearing minerals are mainly ilmenite and titanic magnetite in an iom tailings of Panzhihua. Detailed experiments had been conducted to solve the problems in previous irrational mineral processing, including low recovery of titanium and high grade of sulfur in titanium concentrate. By contrasting several programs, the low intensity magnetic separation - high intensity magnetic separation - spiral chute - electric separation process was ultimately applied, and the titanium concentrate with TiO2 grade of 47. 3 3 % , TiO2 recovery of 55. 13% , sulfur grade of 0. 15% was obtained. This research also provided a reference for subsequent design of process flow.
