Generally, the raw materials can be crushed to 74 μm or 43 μm and then an ultra-fine crushing process can be used. For materials that require very fine particle size and are easy to agglomerate, a multi-stage ultra-fine crushing process in series can be used to improve operating efficiency.

The shaking table is used to separate monazite from lighter siliceous gangue. In the case of fine and ultrafine rare earth minerals, enhanced gravity separators such as Knelson concentrator, Falcon concentrator, and Mozley multi-gravity separators are used. These concentrators use centrifugal force to separate heavier from the lighter particles.

Some fine/ultrafine coal particles may be produced during the grinding process. It is well known that column flotation is suitable for separating fine/ultrafine coal particles smaller than 74 μm (Cinar, 2009, Tian et al., 2017, Xing et al., 2017). Thus, flotation column separation was selected and used in the flotation process.
