4. Magnetic separation: Separation generally adopts permanent magnet drum-type magnetic separator. Most magnetite beneficiation plants often adopt coarse-grained dry magnetic separation tailings. If ultra-lean magnetite ore is below 20.00%, the ultra-fine crushing-wet magnetic separation tailing process can be used before entering the mill. 5.
