As a typical centrifugal gravity separator, the Knelson concentrator (KC) has been widely used to recover gold and platinum minerals because of its remarkable ability (Koppalkar, 2009, Laplante and Gray, 2005, Xiao, 2008, Xiao and Laplante, 2004). The KC was developed in 1978 and was commercialized in 1980 in Canada by Byron Knelson.

Plant testing of a pilot scale Knelson CVD6 was conducted to evaluate ...
The unit that was tested was a pilot scale Knelson Continuous Variable Discharge (CVD6) Concentrator. The primary objective was to determine the effects of the machine operating variables on separation performance; concentrate grade and recovery. The secondary objective was to use the results to develop an operating strategy for the concentrator.
The simulated Knelson concentrator in this investigation was a 7.5-cm (3″) laboratory Knelson concentrator from IMPRC, Iran. The Knelson concentrator inner bowl is made of polyurethane and consists of five collecting rings with different sizes in diameter. This bowl is located concentrically within a cylindrical stainless steel outer bowl. 3.1.

Knelson gravity concentrator has a good effect on gold enrichment, and obtain a high grade of concentrate. The gold content of the concentrate is 251.30 g/t, the recovery rate is 53.70%, and the Knelson has not affected the recovery of copper. 2.3 Advanced analysis …
KNELSON, 3" Lab Model. 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 ...
The concentration mechanism in a Knelson concentrator may thus be linked to a hindered settling classifier • When a particle enters the bowl of the KC it gets suspended in the water and traverses the bowl in a helical motion prior to exiting the bowl if it is not trapped within the rings (grooves).
The population of Knelson Concentrators have increased from a single 7.5 inch Knelson Concentrator in 1988 to 70 units in Ghana and 15 for the rest of West Africa. Knelson Concentrator units are in all parts of West Africa in small, medium and large scale alluvial and hard rock gold mining operations.
