Spiral separators, Gravity Separation
Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
