A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.
The Knelson Semi-Continuous Gravity Concentrator is synonymous with industry-best gravity gold recovery, fine gold recovery and recovery of precious metals. It is highly configurable and available in a range of model sizes that will suit any hard rock or alluvial mining operation.
The Knelson Concentrator relies on an enhanced gravitational force together with fluidization process to recover even very micron sized particles. First water is injected into the rotating concentrating cone through series of fluidization holes. Then feed slurry is introduced through a stationary feed tube. Once the slurry is filled in each cone, create a concentrating bed and high specific
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, can cause dewatering and locking of particles.
A Knelson concentrator is a centrifuge device used primarily in gold mining.The device is a gravity concentration apparatus, which retrieves pieces of fine gold from ore without having to use gold cyanidation, an expensive process that uses chemicals to extract gold from ore.By bypassing this process, Knelson concentrators have become a major
Discussion on the Configuration Forms of Knelson Concentrators in Gravity Separation Process. 1. Preface. In recent years, due to the rapid rise of gold price, the economic benefits of gold mining and production companies have been significantly improved, and a large number of advanced world-renowned mineral processing equipmen t have been applied in China, due to their advantages of high
FLSmidth Knelson Concentrators are the market leaders in gravity concentrators, and are worth more than their weight in gold. Using centrifugal force and water injection processes, FLSmidth Knelson Concentrators create enhanced gravitational forces of up to 200 g’s to recover free gold, fine gold and any other precious metals or minerals with high specific gravities.
The semi-continuous (batch) Knelson Concentrator is the most widely utilised centrifugal gravity concentration device in the industry. Knelson Concentrators combine centrifuge enhanced gravitational force with a patented bed fluidization process to provide unmatched performance in the recovery of precious metals such as gold and fine gold, platinum, silver, mercury and native copper.
Knelson ™ Continuous Gravity Concentrator is an enhanced automated gravity separation system that has been developed specifically to address the requirement for high concentrate mass yield. It can be found operating at numerous sites worldwide providing excellent mineral separation and recovery.
15-06-2020· 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.
With the application of Knelson Concentrator, it has developed from one stage to two stages Knelson gravity separation, and has been applied to the regrinding and classification process of gold concentrate in leaching operation to recover the coarse gold, avoid the deposition loss of coarse gold in the leaching process and improve the recovery rate of gold.
