"A New Generation Of Knelson Concentrators"
A Totally Secure System Goes On Line

B. Knelson and R. Jones
presented at: Minerals Engineering `93 Cape Town, South Africa

July 18th, 1999

This paper briefly outlines some of the traditional gravity concentrating devices commonly utilized in precious metal recovery systems. It summarizes the development of the centrifugal concentrator and, in particular, the problem of overcoming the retention of values while dramatically increasing the g-force. The principles of the Standard Knelson Concentrator are discussed as are those of the recently introduced "Centre-Discharge" (CD) concentrator. The CD model Knelson Concentrator can be fully automated providing a totally "hands-off" and secure system.

"A more recent addition to the Knelson line of concentrators is the "Centre-Discharge" or CD model. This model is manufactured in the three production sizes only, i.e 12" (30cm), 20" (50cm), and 30" (75cm). The CD can be totally automated and integrated into any existing computerized circuit. It provides the mill operator with a "hands-off" secure system while providing the same degree of recovery of free milling gold or other precious metals as the standard unit."

"During a unique short term high grade period we produced 3,000 oz. of gold in a 24 hours operating shift from three XD-48 Knelson concentrators. They are worth their weight in gold." - Marnu Lombaard, Metallurgical Engineer - AngloGold, South Africa ...more > >
