How Antimony is Processed by Flotation
A head-ore sample is cut from the classifier overflow to use as the flotation circuit control and metallurgical balance. A Automatic Sampler is used. Normally the sampling interval is one cut each 15 minutes which is collected each shift as a composite sample. ... The cleaned antimony concentrate is pumped to a Spiral Rake Thickener to …

Mount Cattlin Lithium Project, Western Australia, Australia
The tantalite concentrate is recovered from the DMS pre-screen undersize and undergoes gravity separation using spiral classifiers and wet tables. The tantalite concentrate is contract dressed, while the final spodumene concentrate product from the DMS is stacked on a pad and drained before being trucked to the Esperance Port for export.

Spiral Concentrator Interface Monitoring Through Image …
As the mineral slurry flows down a spiral, smaller heavier particles tend to move to the inside edge of the trough and larger lighter material will move to the outer edge (Loveday, 1994). The separation action of the spiral typically results in the formation of three mineral streams: concentrate, middlings and tailings (Burt, 1984).

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)
