The spiral concentrator applies differential density separation between particles to separate the valuable minerals from the gangue minerals. They have been widely utilized in coal washing plants worldwide to treat material in the particle size range 1 mm–150 μm (other reports show that spirals are capable of treating material down to 45um).

Gravity separation of copper ores Gravity Separation of Copper Ore Beneficiation Production Plants. Generally, crush the copper ores to 0 ~ 5 mm or 0 ~ 9 mm, and then group them by the jigger or shaking table: 1 Separation of lean and rich ores. Some sedimentary primary copper oxide ores are processed by dense media and jigger to remove gangues ...
As seen, the sharpness of separation in dense-media separators is much better than in jigs or water-only hydrocyclones. Figure 24 shows E p values plotted versus the size of treated particles for various cleaning devices.

The angular velocity (ω) is often expressed in terms of the rotational speed, N. w = 2πN/60 where w = 60νr/2πr. The centrifugal force, F c, is given by: Fc = mf (2πN/60)2 = 0.01097 mrN2. Centrifugal force is often expressed in the magnitude of the force with respect to the gravitation force (g's):
