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, …
By using a centrifugal concentrator, with a fluidised feed to stop packing, Byron was able to achieve higher gold recovery levels with less effort and waste, and in 1976 he tested the first Knelson Concentrator prototype. The results spoke for themselves, and with some mechanical fine-tuning the first ever Knelson Concentrator came to fruition.
The Knelson Concentrator takes advantage of the difference in specific gravity between gold and gangue minerals to realize a separation. The centrifugal force magnifies the difference in specific gravity and the rotor geometry facilitates retention of gold particles in preference to low SG particles that are rejected with the process rotor.
The Knelson concentrator (KC) is a vertical axis bowl-type centrifugal concentrator that uses a fluidized bed to perform its …
Laplante et al. (1996) investigated the effects of the feed rate, density and size, and the fluidization water flow rate on the recovery of gold in a 3.5-inch laboratory Knelson Concentrator. They reported that recovery decreased with an increasing feed rate and the effect of the fluidization water pressure was found to be minimal, with the ...
In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in a particle size of 0.004mm, it is up to 97%. Technical data The Gold Centrifugal Concentrator is a centrifuge device used primarily in …
known devices, Knelson Concentrator, was used to separate gravity recoverable golds (GRG) from the gangue minerals of Mandailing Natal (North Sumatera) sulfide complex gold ores with -200# of particle size. The head grade of ores was 5 g/t of gold. The ores were separated by using Knelson Concentrator with variation of pulp density, feeding

The retained mass of material in the Knelson Concentrator (KC) bowl depends on the main forces—the fluid drag force (F d), the centrifugal force (F c), and the buoyancy force (F b)—which act on the particles in the concentrating bowl.They are functions of the material properties, as well as the operating condition parameters.
Press the "run" button. The bowl will start spinning. Feed slurry into the concentrator. The particles must be smaller than 2 mm. After about 30-60 minutes, stop feeding slurry into the concentrator. Reduce the process water pressure. Press the "decrease speed" button until the display shows 5 Hz.
