Abstract
To separate minerals, they are mde up into a slurry applied through feed pipe 46 to a vertical-axis spiralinder 32 spinning on its axis to generate 10 g centrifugal force. The spiralinder is also subjected to axial vibration at 5 to 10 Hz. A film of slurry is held centrifugally to the internal surface of the spiralinder and kept in suspension by the vibration. The denser (i.e. higher specific gravity) particles in the slurry tend to be most firmly pinned centrifugally. The lightest particles thus drop first into the trough 44 and are dumped by switchable box 45. The centrifugal spinning is then slowed and the dense particles scoured off by wash water. The whole cycle is then repeated.
