2016.3.26 Gravity Spiral Concentrator Working Principle. 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)
