The dense medium beneficiation method is used for ores with a particle size of −10 mm + 0.5 mm. The dense medium cyclone is used as the dense medium sorting equipment; tantalite, columbite, or ferrotapiolite suspension is selected as the dense medium; the processing capacity of the dense medium cyclone can reach 50~100 tons …

The sizes of magnetic separators with three types of troughs are as follows: downstream troughs ≤6 mm, reverse troughs ≤1.5 mm, and semi-reverse troughs ≤0.5 mm. The downstream magnetic separator has a large processing capacity and is suitable for the rough separation and cleaning of the stronger magnetic materials with a coarser size.
