Spirals are helicoid troughs fixed at a declining slope and arranged in 7-, 5-, or 3-turn configuration. Slurry feed containing sand and water is introduced at the top of each spiral. As the material flows down and around the troughs, the lighter minerals such as quartz and silica sand are carried to the outside of the stream.
