To effectively recover titanium resources in the tailings from a titanium processing plant and improve the relative utilization rate of raw ore, beneficiation of the tailings with a TiO2 grade of 5.81% from the tailings pond was studied. A gravity and magnetic separation process were proposed and the influences of magnetic field intensity, rising water flow rate, feeding rate and feeding concentration on ilmenite separation indices were studied. The results show that after a gravity separation of +38 μm range, a gravity separation of underflow from -38 μm classification and magnetic separation of overflow from -38 μm classification, a rough concentrate with TiO2 grade of 16.08% was obtained at recovery of 62.63%, while tailings with a yield of 77.41% and TiO2 grade of 2.39% was cast off. Consequently, the feeding amount of succeeding flotation can be greatly reduced.
