摘　　要：云南文山某钛铁矿原矿含TiO25.96%,以钛铁矿为主,还含有少量的金红石。原矿经磨矿分级控制入选粒度为-0.5 mm,采用水力分级后重选,水力分级粒度为0.038 mm,重选工艺流程为螺旋溜槽粗选、摇床精选,得到品位46.67%,回收率59.01%的钛精矿。该工艺流程简单,投资小、选矿成本低。The run-of-mine of ilmenite in Wenshan,Yunnan province contains the content of TiO2 5.96%.It mainly exist in the type of ilmenite and a little of rutile.The feeding particle-size is controlled to be about-0.5 mm through the grinding and classification system.The hydraulic classification size is 0.038 mm with the hydraulic classification gravity separation.Through the gravity flow-sheet of ＂roughing by spiral chute and cleaning by tabling＂,the titanium concentrate grading at 46.66% with a 52.35% recovery was obtained.This flow-sheet owns features of simple processing,low investment,and low costs in beneficiation.
