The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance.
Both test programs were conducted using a pilot scale Knelson CVD6 concentrator. At UBC, the pilot scale testing facility consists of an agitated feed tank, a slurry feed pump for the CVD6 concentrator and a Sala pump that pumps the combined products (concentrate and tailings) to a storage tank. At the end of a test the combined
Using Knelson gravity concentrators, about 50% of the gold is easily liberated and recovered as free gold at Blanket Mine in Zimbabwe . Knelson gravity concentrators …
Knelson concentrator is generally operated at 60–100 g' in most applications, although it can go up to 180 g' [27, 28]. The Knelson concentrator is also classified into two types, i.e., batch and continuous type. The difference between batch and continuous type concentrators is presented in Fig. 4.
MODELING OF KNELSON CONCENTRATOR OPERATING PARAMETERS 119 JOURNAL OF MINING SCIENCE Vol. 59 No. 1 2023 One of the most common enhanced gravity separators, Knelson concentrator is essentially a vertical axis bowl-type centrifugal concentrator which operates with a fluidized bed to concentrate the fine size material [6].
Knelson ™ Continuous Gravity Concentrator is an enhanced automated gravity separation system that has been developed specifically to address the requirement for high …
The objective of the present study is the derivation of an empirical model of material separation inside the Knelson Concentrator in terms of particle characteristics (size and density) and operating condition parameters (rotational speed and fluidization water pressure, etc.). This model can be used, firstly, to predict the separation of GRG ...
For decades, Knelson™ concentrators have been synonymous with industry-leading gravity recovery of fine gold and precious metals.

The Knelson concentrator is a centrifugal separator which was originally and successfully designed for extracting free gold particles. Despite of its wide range of applications, the exact concentration mechanism of the device is not fully understood. The purpose of this research was to determine the optimum parameters and improve the …
CONCENTRATION – Byron Knelson Benjamin Virgil (Byron) Knelson (1930-2011) developer of the Knelson concentrator is a titan of gravity separation. Almost 40 years ago a pursuit to discover a 'better way' would revolutionise the application of gravity separation in the gold mining industry. Today, this
The Knelson Concentrator was at the forefront of utilising centrifugal forces in the gravity concentration of gold, with LaPlante et al. instrumental in developing the Gravity Recoverable Gold (GRG) Test which is still in use today (Laplante et al., 1995a, 1995b; Laplante et al., 1996). Centrifugal separators are not limited to gold (Gul et al ...
