Dispelling the myth: There are abundant documented cases of FL Knelson Concentrators recovering extremely fine gold – "paint" or "powder" gold that floats on water – and in some trials and installations in Africa, FL Knelsons have recovered this very fine gold downstream of competitor products that claimed to be better suited for the job.
A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.
The centrifugal concentrator rotates at a high speed, generating a high "G" force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables. In recent years, the application of centrifugal force has proved to be an ...

· Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.

· Study on Knelson Concentrator Gravity Separation of a Polymetallic Ore Bearing Gold. The major methods of recovering gold are gravity separation, gold flotation, cyanide. In fact, traditional gravity separators, such as jig machine, spiral chute, gold shaker table, have the shortages of low beneficiation ratio and low productivity.
High gold recovery with fully fluidised cones. Our concentrator''s leading-edge cone technology has been built on 40 years of innovation and is designed to capture the maximum amount of gold per cycle. Knelson is the only enhanced gravity concentrator with a fully fluidised bed allowing for upgrading throughout the entire cone surface.
· Gold Knelson centrifugal concentrator. In actually gold ore plant operations, all gravity concentrates are further upgraded using shaking tables. These tables typically yield gold recoveries between 75 and 90%. The gold losses are due to incomplete liberation only in part, and in fact, result mostly from fines and flakes.
