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 gold recovery with fully fluidised cones. Our concentrator’s leading-edge cone technology has been built on 40 years of innovation and is designed to capture the maximum amount of gold per cycle. Knelson is the only enhanced gravity concentrator with a fully fluidised bed allowing for upgrading throughout the entire cone surface.
Apr 25, 2019· Knelson concentrator is an efficient centrifugal gravity separation equipment, suits for recovering precious metals such as gold, silver, platinum group and other heavy metal minerals, and has become one of the most used gravity separation machines. Advantages of Nelson concentrator: High beneficiation ratio.
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
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 equipment have been applied in China,these equipment include: crushing and screening equipment produced by Metro and liming, Knelson Concentrator, etc.
RECOVERY OF PLACER GOLD The tests with the 7.5 inch Knelson Concentrator were carried out under the following operating conditions: pulp dilution, 3 : 1; particle size ,-10 Tyle r mesh; grade, different for each test (30099-96326 mg/m3); the feed flowrate, 0.22 m3/hr; and water pressure, in the range of 4 to 6 psi. The results are shown in
Dispelling the myth: There are abundant documented cases of FLSmidth Knelson Concentrators recovering extremely fine gold “paint” or “powder” gold that floats on water and in some trials and installations in Africa, FLSmidth Knelsons have recovered this very fine gold downstream of competitor products that claimed to be better suited for the job.
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks. Place a receptacle under the barrel to
