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 tanks and thereon into the final tails. (See fig. 4)

Grinding

Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The selfgrinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.
