Comparing the Knelson vs. Falcon Gravity …
21.06.2020 · The overall bowl angle of the Knelson concentrator is approximately 13 degrees from vertical. Because this angle is shallower than the dynamic slurry face, the slurry can freely exit and there is no slurry face created in the bowl. Like the riffles in a sluice box, the Knelson riffles create small eddy currents as the slurry falls over each riffle. These eddy currents disturb the bed of material and help to …
Knelson-Concentrators -in-Gravity-Separation …
With the application of Knelson Concentrator, it has developed from one stage to two stages Knelson gravity separation, and has been applied to the regrinding and classification process of gold concentrate in leaching operation to recover the coarse gold, avoid the deposition loss of coarse gold in the leaching process and improve the recovery rate of gold.
Knelson Concentrators - Consep - Engineering …
The semi-continuous (batch) Knelson Concentrator is the most widely utilised centrifugal gravity concentration device in the industry. Knelson Concentrators combine centrifuge enhanced gravitational force with a patented bed fluidization process to provide unmatched performance in the recovery of precious metals such as gold and fine gold, platinum, silver, mercury and native copper.
Gravity concentration systems – for enhanced …
The Knelson Semi-Continuous Gravity Concentrator is known globally for its leading capabilities in gold recovery, fine gold recovery and the recovery of other precious metals. It is available in a range of model sizes that will suit sites’ requirements. It is highly configurable and has a capacity range from laboratory scale up to 1000 tonnes of solids per hour.
Knelson Concentrator
The Knelson Concentrator relies on an enhanced gravitational force together with fluidization process to recover even very micron sized particles. First water is injected into the rotating concentrating cone through series of fluidization holes. Then feed slurry is introduced through a stationary feed tube. Once the slurry is filled in each cone, create a concentrating bed and high specific ...

Knelson Concentrator A 3 inch batch concentrator (model number: KC-MD3), typically useful for recovering fine liberated precious metals at a laboratory scale.
Gold Recovery with Centrifugal Gravity …
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. Place a receptacle under the barrel to collect the ...
CONCENTRATION – Byron Knelson
Benjamin Virgil (Byron) Knelson (1930-2011) developer of the Knelson concentrator is a titan of gravity separation. Almost 40 years ago a pursuit to discover a ‘better way’ would revolutionise the application of gravity separation in the gold mining industry. Today, this application continues to improve cash-ow for operations around the globe.
KnelsonConcentrators -in-GravitySeparationProcess
The undersize material is fed into the Knelson Concentrator for gravity separation and recovery of coarse gold. The tailing of Knelson Concentrator are pumped to the classifier for classification. The configuration form is shown in Figure 3. Figure 3 Process Configuration of Fixed Sieve, Knelson Concentrator and Spiral Classifier. The advantage of this kind of configuration form is to make ...

09.07.2018 · Here is a quick video featuring a real ore sample that contained coarse gold recovered by gravity concentration. Met-Solve uses a lab-scale centrifugal concentrator unit to test how much of a ...
Gravity Separation | FLSmidth Knelson Gold …
“ The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ores, especially smaller high value deposits.
Falcon SB Gravity Concentrator | Mineral …
A typical application for a Falcon SB Gravity Concentrator is recovering liberated precious metals (Au, Ag, Pt, etc.) within a grinding circuit. Outside grinding circuits, Falcon SB Gravity Concentrators are also used for precious metal separation from aggregate or placer deposits.. Falcon SB Gravity Concentrators are known as “Semi-Batch” Gravity Concentrators because they continually ...
