Gravity Spiral Concentrator Working Principle

7/4/2018 The gravity spiral circuit is designed to extract and concentrate “coarse gold’ from the recirculating load in the mill grinding circuit and hence prevent a build up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails.

Spiral (Concentrators) an overview ScienceDirect Topics

15.5.3 Spiral Concentrator. The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral, for the separation of chrome-bearing sands in Oregon. By the 1950’s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.

Effect of Operating Parameters on the Performance of

Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used to treat chromite ore in 1943. Later in 1943, its use was extended to the mineral sand beneficiation. Since then Spiral design has been progressively modified to improve operational features

Spiral separator Wikipedia

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to

Mineral processing Wikipedia

Of the gravity separation processes, the spiral concentrators and circular jigs are two of the most economical due to their simplicity and use of space. They operate by flowing film separation and can either use washwater or be washwater-less. The washwater spirals separate particles more easily but can have issues with entrainment of gangue with the concentrate produced.
