The spiral separator is suitable for processing alluvial gold ore, especially for gold ore with a high degree of monomer dissociation and flat shape. Besides, it is also good at dealing with fine gold ore with particle sizes between 0.003-0.6mm containing low mud content. Spiral chutes are often used for rough concentration. What we love:

The separation of ore particles in the medium is driven largely by the centrifugal forces which they and the medium experience. The centrifugal force, F c, on an ore particle entering with the medium at the periphery of the cyclone is given by: (A2) F c = mV i 2 r where m is the mass of the particle and r is the radius of rotation, here ...

The method is used for fine ore in the size range of - 6+ 0.2 mm. The cyclone type separation utilizes centrifugal as well as gravitational forces to make separation between ore and gangue minerals. The centrifugal force makes it possible to bring about separation at a specific gravity lower than that required in the conventional separator.
