mineral processing - Concentration | Britannica
Finer-grained particles (from 1 millimetre to 50 micrometres) can be effectively separated in a flowing stream of water on horizontal or inclined planes. Most systems employ additional forces—for example, centrifugal force on spirals or impact forces on shaking tables. Spirals consist of a vertical spiral channel with an oval cross section.

Mineral Sands | Strandline Resources Limited
The heavy mineral is separated from the quartz sand. In the case of spiral technology, the spiral troughs are angled and the heavy mineral sand moves to the inside and the lighter gangue minerals to the outside of the trough as the slurry travels down the spiral. Repulpers on the spirals aid in the recovery process.

Spiral separator - Wikipedia
For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; [3] and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape.
