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
