摘　　要：攀枝花某高铬型钛磁铁矿矿石中含有丰富的钛磁铁矿和钛铁矿资源,文章根据该矿石钛磁铁矿及钛铁矿等有用矿物的赋存状态,研发出“两段磨矿-磁选-磁浮选”分离回收钛磁铁矿和“两段强磁选-脱硫浮选-钛粗选-精选”回收钛铁矿的磁浮联合工艺流程,全流程闭路试验可获得产率34.20%、TFe品位55.71%、TiO_(2)品位13.46%、TFe回收率70.54%、TiO_(2)回收率50.87%的钛磁铁精矿以及产率4.86%、TiO_(2)品位48.25%、TiO_(2)回收率25.91%的钛精矿,高铬型钛磁铁矿中钛磁铁矿及钛铁矿得到有效回收。There are abundant ilmenite and titanomagnetite resources in a high chromium titanomagnetite ore inPanzhihua.The combined process of two stage grinding-magnetic separation-magnetic flotation for recovery oftitanomagnetite and two stage high gradient magnetic separation-flotation desulphurization-ilmenite roughing-cleaningfor recovery of ilmenite has been developed in this paper which is based on the existential fom of the useful mineralsin the ore such as titanomagnetite and ilmenite.The test index of the titanomagnetite concentrate with yield of 34.20% and TFe grade of 55.71% and TiO_(2) grade of 13.46%and TFe recovery of 70.54% and TiO_(2) recovery of 50.87% and the ilmenite concentrate with yield of 4.86%and TiO_(2) grade of48.25%and TiO_(2) recovery of 25.91%were obtained in closed circuit test The titanomagnetite and ilmenite in high chromium titanomagnetite ore areefficiently recycled.
