Knelson Concentrators are gravity concentration devices that are commonly used in gold recovery from both alluvial and primary ore deposits (Coulter and Subasinghe, 2005, Zhang, 1998). The device is installed in the grinding circuit of a gold operation, where the metal often accumulates due to its grinding and classification behaviour (Banisi ...

Knelson™ and Falcon Concentrators Popularized Gravity Centrifuges. The development of fluidized gold centrifuges has a rich history, starting in Australia in the 1930's. However, the equipment was not popularized until the development of the Knelson™ and Falcon concentrators in the 1980's.. The Knelson™ concentrator consists of an inclined, …
Knelson Concentrators adopted and used these procedures to develop their KC-MOD*Pro circuit simulator, which allows accurate modelling of plant recovery on the basis of lab test results. GRG, EGRG and modelling now allow fully informed decisions about gravity processing to be made long before the casting of first concrete on a new …
"The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ores, especially smaller high value deposits.
