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)

to settle. The settled grit travels up the spiral conveyor where it is de-watered and then discharged as a low moisture product ready for final disposal. The balance, containing light organics and grit finer than 150 mesh, flows over the classifier overflow at the end of the classifier where it can be piped for further treatment. 1. Cyclone ...
