A Knelson or Falcon concentrator is designed to process fine, free gold that does not require cyanidation for recovery. These use the principle of centrifugal force which aids in the separation process based on the particle density. In the laboratory, these generally are operated as batch processes but can be made to operate continuously.
Apr 26, 2013· Cyclones work because the mass of the particle is sufficient to throw it against the outer wall of the cyclone where it can be separated from the flow as a whole. Think of spinning something on the end of a rope - as the centrifugal force of the spinning water works, the particle is …

Fine Gold Recovery Systems Inc. is also one of thousands of applicants we ...
A ratio of 2.5:1 is perhaps 'perfect'. In other words, if you're feeding the sluice 1/4" gravels the maximum riffle height should be 3/4" or less as an example. The 'perfect' height for 1/4" gravels would be 5/8" but this riffle height would be a custom fabrication. Almost all 'mass-produced' riffles are far too high for ...
During this first part of the downswing, the upper lever is providing nearly of the momentum to the swing. As we get further into the downswing, the outward pull of centrifugal force causes the second lever to begin to catch up with the first. Momentum is being transferred through the law of conservation of angular momentum.

Nowadays, centrifugal concentrator is widely used for the recovery of gold, tungsten, ...
1. Centrifugal concentrator is more effective for the treatment of micro slime, and the recovery rate for grain fractions of 37 to 19 micron is as high as about 90%, because the separation of mineral grains in a centrifugal concentrator is based on the combined effect of centrifugal force and lateral flow membrane., so the total enrichment ratio is higher than the plane gravity chute;
