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.

By recovering 15% of the feed mass on a small Falcon C1000 (30t/h) and treating only 12% of the cyclone underflow, one can easily recover over 80% of the gold by using continuous Falcon gravity units in the grinding circuit. Typically a batch type concentrator would be treating greater than 20% of the cyclone underflow.
