A Knelson Concentrator recovered 9.8% gold and 0.5% silver. The gravity tails reported to a cyanidation circuit that has 14 hours pre-treatment and 116 hours leaching. The Kupol mill overall gold and silver recoveries for 2008 were 95.4% and 85.6% respectively, which were 2.8% and 7.5% higher than targets.

Gravity concentration was achieved with pinched sluices and 76cm Knelson bowls, with a significant increase in fine gold recovery. Again, the first material fills the rings completely. At this point, any similarity in the two centrifugal type concentrators begins to separate as the unit greatly enhances and improves the centrifugal factors.

Knelson Concentrator (KC) as a centrifugal concentrator is mainly used for recovery of gold and platinum and may be used for recovery of heavy minerals in alluvial mining, grinding and flotation circuits products (Coulter and Subasinghe, 2005, Kelson and Jones, 1993, Laplante et al., 1994, Zhang, 1998). The device is most commonly installed ...

The Knelson Continuous Gravity Concentrator was developed to address specific mineral recovery applications which semi-batch-concentration methods are unable to achieve. It is the only continuous gravity concentrator that utilises fluid-bed technology and avoids non-fluidised flowing film separation which, when used at higher G-forces, …

Metallurgists operating Knelson Concentrators (KC) often rely on manufacturer's recommendations for selecting operating parameters, such as fluidising water flow rate and cycle time. Recent studies have shown that these parameters are not only dependent on the machine parameters but also on the feed characteristics, such as size distribution of the …
