May 24, 2020· KC has been extensively used to recover gold from alluvial and primary ore deposits because it can achieve very high gold recoveries over a wide size range (Knelson, 1992, Coulter and Subasinghe, 2005, Koppalkar, 2009, Laplante, 2000, Meza et al., 1994).In the previous three decades, numerous laboratory and industrial studies have evaluated …

Through all those years, Knelson has been widely accepted as the gold standard of gravity recovery. Not long after the first Knelson was unveiled, other companies and would-be manufacturers picked up on the idea and tagged along. So they have also been around for some time, but 40 years on FL Knelson still has over 80% of world market share.

As Jamie points out the parameters for the Knelson are application specific. The mass pull from an XD20 is cone dependent, I've attached the spec sheet which has this information for each of the three cone possibilities (G5, G6, and G7). As for concentrating time this will be based on; of size distribution of the GRG (gravity recoverable gold),

GCA has successfully commissioned two KC-QS48/ICS FL Knelson Concentrators at Asanko Gold 's project in Ghana. The KC-QS48s at Asanko are each rated at 400 tph solids (40-70% solids in feed pulp). The plant design was a fairly 'standard' and well-proven design, which incorporated a coarse crusher, SAG mill, and a Knelson concentrator.

Nov 01, 2020· The Falcon concentrator and KC comprise a vertical, conical, open-topped bowl mounted on a rotating shaft and work on the combined principles of centrifugal separation and fluidized bed separation. The bowl of the Falcon concentrator can be classified as the migration zone (lower section) and retention zone (upper section), …

ABSTRACT. Enhanced gravity concentrators such as Knelson concentrator (KC) are extensively used in the mineral processing industry. The complexities of KC bowl geometry and variation of feed characteristics have forced process engineers to design empirically new units using laboratory and pilot-scale Knelson concentrators.

Mar 01, 2016· Knelson Concentrators outshone any and all predecessors in recovering precious metals, and set the standard in the gravity concentration of free-milling gold and platinum. Essentially, the concentrator is a centrifuge that combines enhanced gravitational force with a water injection process to create a fluidized concentration surface into which ...
