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 concentrators will tolerate minor feed variations without requiring adjustment. Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large- scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).
Another area where the new generation of spirals may result in the redesign of spiral circuitry is the production of silica sand for glass manufacture. In this industry the requirement is for a clean sand product rather than a high grade heavy mineral concentrate.
