Furthermore, dry separation technologies for lignite beneficiation should be developed in the future, which avoid the drying process for lignite after wet beneficiation. Dry beneficiation is suitable for coal preparation in arid or semiarid regions. (3) Magnetic separation is for the dry desulfurization process of lignite.
