Research of dressing iron from products of V-Ti magnetite from Panxi ultra-finely comminuted by HPGR

Experiments of dressing iron using process of parallelly separating Fe and Ti were conducted on -3.2mm V-Ti magnetite from Panxi ultra-finely comminuted by HPGR.When the grinding fineness of concentrate of ultra-finely comminuted products by HPGR sorted by wet magnetic separator for coarse particle is -0.074mm 45%,the Fe grade of concentrate is 55.05% and the recovery is 70.64% after two stages of magnetic separation.The performances are similar to that obtained by stage-grinding and stage-magnetic separation of the same products crushed by Jaw.But the energy consumed of the former was reduced obviously.
