Spiral (Concentrators)
For processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the outside.
