The Knelson™ Concentrator vs. Falcon Gravity Concentrator
Knelson™ and Falcon Concentrators Popularized Gravity Centrifuges. The development of fluidized gold centrifuges has a rich history, starting in Australia in the 1930’s. However, the equipment was not popularized until the development of the Knelson™ and Falcon concentrators in the 1980’s.. The Knelson™ concentrator consists of an inclined, The results of gravity tests have indicated that 81% of the gold from the ground ore (-74 μm) can be recovered into a concentrate (Con.1) with a grade of 262 g/t Au at a 7.2% yield.

Determining the Separation Performance of the Knelson
Knelson concentrator Being an EGS technology, the Knelson concentrator op-erates based on teeter-bed principles in a centrifugal field to separate fine particles (Honaker et. al. 2005) Fig. 1 shows schematic illustration of a Knelson concentrator. This concentrator is a vertical axis bowl-type centrifugal concentrator and utilizes a fluidizedThese 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).A design of experiments investigation into dry separation using

The potential for dry processing using a Knelson Concentrator
The possibility of dry processing using a Knelson Concentrator has been shown to have potential by Greenwood et al. (2013), with optimizing and modelling of dry Knelson process having recentlyFalcon concentrators are enhanced gravity separators (EGS) consisting of a fast spinning bowl. The bowl is fed from its bottom and uses centrifugal force to drain the slurry in a thin flowing film at its wall. During operation, part of the transported particles is retained inside the bowl, while the other part flows out with the fluid.Physical analysis and modeling of the Falcon concentrator
