Spiral Separators VS Concentrating Tables
The typical spiral unit consists of a spiral conduit with a modified semi-circular cross section. As the slurry flows down the spiral, those minerals with highest specific gravity move to the inner edge of the spiral while the light material moves upward to the outer edge of the spiral. A full size spiral concentrator is shown in Figure 2.

Spiral Concentrators — IMSC Group
Spiral Operation. Slurry enters the spiral through a feed box and is introduced on to the spiral surface. Once on the spiral surface, the mineral grains settle and sort according to size, shape and specific gravity. Generally, the particles with the lowest specific gravity are carried with the water towards the outside wall of the spiral.
