The "Condor" Dense Media Separator is a dynamic cylindrical separator. In the DMS unit, the dense media is pumped from the lower end of the cylinder (medium inlet 1 and 2) as shown in . Figure 1. Utilising gravitational and centrifugal forces, a tangential or involute inlet forces the media to spiral alongside the wall, creating a vortex ...
Gravity separation process and strong magnetic separation process are mainly used to separate coarse-grained (2mm-20mm) and medium-grained weakly magnetic iron ore. Among them, coarse and extremely coarse (greater than 20mm) ores are commonly used in heavy medium or jigging gravity separation technology;

Supporters of dense medium separation claim that this technology is proven to provide the best possible separation and that the gain in efficiency over the life of the plant, compared to that of a jig, will more than offset any differences in capital or operating costs.
In summary, iron ore was separated into gangue as floaters and valuable ore as sinkers in a dry dense medium of gas-solid fluidized bed using zircon sand as a fluidized medium. The set point decreases with increasing the air velocity. u0 / umf = 1.2 is an optimum air velocity to separate gangue and valuable ore at a set point of 2850 kg/m 3.
Dense media separation (DMS) or heavy media separation is a pre-concentration technique used to reject gangue minerals prior to grinding. DMS exploits the difference in specific gravity between the target and gangue minerals, and is commonly used in the separation of spodumene from other gangue silicates.
The ore particles of 6 100 mm in size are treated by the wet dense medium separation, for which the density of the dense liquid is adjusted at 27503150 kgm 3. although development of dry separations for iron ore is strongly needed, the dry dense medium separation has not been tested for iron ore.
