The separation canister is shown in Fig. 3, which was used to recover ultrafine ilmenite under the high magnetic gradient produced by a specific magnetic matrix with a filling rate of 6%. A linear drive motor was used to drive the separation canister reciprocating motioned in the bore under an applied magnetic field.

02 Ilmenite magnetic mineral separation process. Ilmenite is a weakly magnetic mineral and has greater magnetization under the same volume and size. When magnetic separation is performed, if the magnetic field strength is not enough, some useful minerals will be thrown away, thereby reducing the utilization rate of the minerals.
