Gravity Spiral Concentrator Working Principle - 911 Metallurgist

Oct 8, 2017 ... 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. (See fig. 4)...

Spiral separator - Wikipedia

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...
