These impart acceleration up to 300 times that of Earth's gravity, in order to enhance the separation. At the forefront of this were the Knelson Concentrator and the Falcon (Knelson, 1992; Lins et al., 1992; Honaker et al., 1996; Chatterjee, 1998; Laplante and Spiller, 2002; Kroll-Rabotin et al., 2010; El-Midany and Ibrahim, 2011).

MODELING OF KNELSON CONCENTRATOR OPERATING PARAMETERS 119 JOURNAL OF MINING SCIENCE Vol. 59 No. 1 2023 One of the most common enhanced gravity separators, Knelson concentrator is essentially a vertical axis bowl-type centrifugal concentrator which operates with a fluidized bed to concentrate the fine size material [6].
Knelson concentrators are the most widely used semi-continuous centrifuge separators ... characterization studies on these units provide information about the occurrence of gold in ore samples (e.g. gold particle size distribution, amount of gold recoverable by gravity) but not about the effect of operating variables for full-scale units such ...
Read these papers and try to Compare Falcon & Knelson Concentrators only to find out; they perform the same. Both use high gravity centrifugal forces to separate gold from ore with similar results. Do no be fooled by the propaganda. The laws of gravity apply to everyone whether you believe in them or not.
Falcon gravity separation equipment is proven to outperform Knelson gravity concentrators when it comes to gold recovery. Read the whole study here.
By 2010, Knelson Concentrators had become so successful that it entered into negotiations with FL, to further expand the operations of Knelson, whilst also taking care of his loyal Knelson Concentrators brethren. After a year of negotiations, on 29 August 2011, Byron passed away, succumbing to his struggle with cancer.
Semi-continuous units, such as the Batch Knelson and Falcon SB, have been widely accepted for recovery of free gold within grinding circuits. Fully continuous machines (Kelsey Jig, Falcon C, Knelson CVD) that can recover mass yields as high as 50 per cent have yet to find their niche. Extending the particle size
Knelson Concentrator. The Knelson Concentrator relies on an enhanced gravitational force together with fluidization process to recover even very micron sized …
Notable examples of such separators include the Knelson concentrator (KC), Falcon concentrator, Kelsey jig, and multi-gravity separator (MGS). The Kelsey jig and MGS use an additional separation mechanism, i.e., stratification is used in the Kelsey jig, whereas shaking is used in the MGS (Majumder and Barnwal, 2006, Das and …
The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. ... after pre-concentration to recover liberated gold particles early on). Falcon and Knelson concentrators are the most popular models (Q. Chen et al., 2020; Kroll-Rabotin et al., …

These mineral systems include run off mine ore, secondary products like tailings and plant slags, etc. For this purpose, the design, operational features, types, and separation mechanism of enhanced gravity separators, such as Falcon concentrator, Knelson concentrator, multi-gravity separator (MGS), and Kelsey Jig, are discussed.
The Falcon gravity concentrator outperforms the Knelson in recovering fine gold. Learn about the applications where the Falcon is used for fine gold recovery.
It has now become almost an essential unit operation in any gold processing plant to assess the gravity recoverable gold content in the ore as well as to recover fine free gold from the grinding circuit. Knelson Concentrator (KC) first introduced to the hard rock milling industry there-by providing gold recovery by handling a maximum feed size ...
Highlights 3″ Knelson Concentrator has been configured to operate under dry conditions. Synthetic ore of tungsten and silica was used to mimic a gold ore. The tungsten recovery at 2 psi air fluidisation was greater than 78% (grade of 6%). The tungsten recovery at 3 psi air fluidisation was 69% (tungsten grade 15%). The potential to operate …
