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.

Centrifugal gravity concentrators provide an advanced level of separation in mineral processing as compared to conventional gravity concentration methods and tools ... as known, the main application niche of these concentrators is in gold processing. The sampling, assaying, identification work and modelling are general problems …

The Knelson Concentrator is a compact hatch centrifugal separator with an active fluidized bed to capture heavy minerals. A centrifugal force up to 60 times that of gravity acts on the particles, trapping denser particles in a series of rings (riffles) located in the machine, while the low-density particles are flushed out.

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the ...

Centrifugal Gravity Concentrators. Written By: Team Sepro | Date: 03.05.19. In the last 20 years, advancements in the design and operation of centrifugal gravity concentrators have made them the predominant method for gravity concentration of gold. Further advances in recent years has expanded the use of this technology for …

Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times.
