separation and eventually sorting different particles [2]. When water is removed, and air plays the role of separation medium, the separation method is defined as dry, pneumatic, or air gravity separation [3]. In general, dry gravity separation has the attraction of decreasing capital and operating costs compared to the wet mode.
