WHAT is a KNELSON CONCENTRATOR?

A Knelson concentrator can best be described as a high-speed centrifuge that combines centrifugally enhanced gravitational force with a patented fluidization process. This combination provides unequalled performance in the recovery of free gold.

The concentrating cone is made of a highly wear resistant polyurethane compound which is cast into a stainless steel shell. The conical shape is comprised of a series of horizontally segmented rings; increasing in diameter from bottom to top. Around the circumference of each ring is a series of fluidization holes that enable the injection of water into the ring. The precise size, number and location of these holes is the result of extensive research and on-going product development. The concentrating cone is installed into the rotor housing, thus creating a water chamber.

Fluidization water is introduced to the water chamber through the rotor shaft. Once the chamber has filled to capacity, the water is then forced through the fluidization holes and into the concentrating rings. This injection process is done tangentially in a counter-clockwise direction.
Knelson Concentrators are typical installed to recover free gold from cyclone underflow material on gold recovery plants.

Machines models ranges from a 45kg per hour laboratory model KC-MD3 to a 650-1000tph KC-XD70 unit.

Since its introduction in Ghana in 1988, Knelson concentrators have become a standard in gold recovery plants in Ghana and the entire West African Region.

The population of Knelson Concentrators have increased from a single 7.5 inch Knelson Concentrator in 1988 to 70 units in Ghana and 15 for the rest of West Africa.

Knelson Concentrator units are in all parts of the country in small, medium and large scale alluvial and hard rock gold mining operations.

20% (average) of all gold produced in hard rock operation in Ghana are from Knelson Concentrator Installations

Upcoming installations are for Newmont And Chirano Gold Mines this year – 2005/2006
Newmont Gold have purchased 2x 300tph Knelson Concentrators (2x KC- XD48). The new machines are expected to be installed in 2005/2006

Chirano Gold Mines will be installing a 300tph KC-XD48 Knelson concentrator unit by the 3rd Quarter of 2005.
