Washwater spirals require the addition of water at various points down the spiral providing more efficient washing of the concentrate, i.e., transporting away light gangue (silica) from the concentrate band. Principle of separation. During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface.

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.

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral …

1.3 Criteria for size separation New model spiral separators have now been developed that are specifically designed to treat material finer than 0.1 mm (100 µm), (Richards et al., 2000). This fine mineral spiral separator is typically longer than traditional troughs to allow these very delicate processes to produce an adequate separation.
