Spiral Concentrators - Mine Engineer.Com provides

Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG's of at least 1.0.

Gravity Spiral Concentrator Working Principle

Mar 26, 2016  The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling.

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.
