Dense Medium Separation
Dense medium separation is also used for some auxiliary operations: (1) Raw material preparation: These include crushing and screening, which are intended to allow the processed material to have certain particle size. The upper limit of particle size is so designed that the material flow will not cause clogging in certain diameter.

Chapter 3 Gravity Separation
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.
