Gravity Spiral Concentrator Working Principle

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)

Rake Classifier

rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …
