摘要/Abstract

摘要： 对攀西钒钛磁铁矿进行了高压辊磨超细碎及其选别试验.当入料d80为155mm时，辊压中料-32mm产率为9105%，-0074mm产率为1529%，P80降低至155mm，边料及闭路循环工艺对粉碎产品粒度特性的影响也非常明显.采用“铁钛平行分选”工艺对高压辊磨超细碎的-32mm攀西钒钛磁铁矿进行了选别试验.结果表明，选铁流程在磨矿细度为-0074mm占45%时，铁精矿Fe品位可达5505%，回收率7064%；选钛流程在-0074mm占80%时，钛精矿TiO2品位4778%，回收率3516%.

Abstract: Experiments of ultrafine comminution by HPGR and separation on VTi magnetite in Panxi were done. When d80 of feeding is 155mm，the yield of -32mm for the roll grinding centre product is 9105%，the yield of -0074mm is 1529% and P80 of roll grinding products is reduced to 155mm. The effect of circulation technology of edge product and closedcircuit on the size characteristics of crushed product was very obvious. Separating tests were performed on -32mm Panxi VTi magnetite from ultrafine comminution by HPGR using process of parallel separation of Fe and Ti. The results show when grind fineness is -0074mm 45%， Fe grade of iron concentrate is 5505% and recovery is 7064% in iron separation flowsheet， while TiO2 grade of titanium concentrate is 4778% and recovery is 3516% in titanium separation flowsheet at -0074mm 80%.

Key words: highpressure grinding roll(HPGR), interparticle comminution, ultrafine comminution, VTi magnetite in Panxi, parallel separation of Fe and Ti
