The Knelson concentrator KC is a vertical axis bowl-type centrifugal concentrator that uses a fluidized bed to perform its concentrating duty. It was first introduced as a semi-batch unit and has gone through several iterations of design leading to the development of a continuous discharge machine. It has now become almost an essential unit operation in any gold processing plant to assess the gravity recoverable gold content in the ore as well as to recover fine free gold from the grinding circuit.
Knelson ConcentratorKC first introduced to the hard rock milling industry there-by providing gold recovery by handling a maximum feed size of 6 mm. More recently KC-XD30 is rated to process 60 th of feed solids.
These are obviously the pre-requisites to explore its possibilities for other applications.
Equip yourself with the gold standard. Overview. The Extended Duty semi-continuous batch Knelson Concentrator KC-XD is the premium class of centrifugal concentrators available today and has been designed to withstand the severe operating conditions inherent to hard rock milling circuits. Manufacture and Design. Model KC-XD48 Serial ...
A schematic diagram of the Knelson Concentrator is shown. It has gone through several modifications, since its introduction as a semi-batch unit in 1982 to a continuous mode of operation Knelson and Jones, 1994. The equipment essentially has a 8216V8217 shaped cone with a series of parallel riffles and many small holes inside the cone. The cone rotates at a speed of 1500 RPM, producing a centrifugal force of 60 g. Water is fluidised through the small holes and the lighter particles are carried away by the water to tailings stream.
The Knelson Semi-Continuous Gravity Concentrator is synonymous with industry-best gravity gold recovery, fine gold recovery and recovery of precious metals.
Gold centrifugal concentrator also called knelson concentrator is a new type of gravity concentration equipment, used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.
Gold, silver, platinum, tin, tungsten, lead, antimony, chrome, titanium.
It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
After the ore was dissociated, a large part of gold became granular gold, and it was difficult to achieve effective recovery by flotation, so the Knelson is used to pre-recover the granular gold. 2.1 Sample Screening. The Knelson centrifugal concentrator is often arranged at the outlet of the ball mill, we analysis the ball mill discharge ...

Discussion on the Configuration Forms of Knelson Concentrators in Gravity Separation Process. 1. Preface. 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 equipmen t have been applied in China, due to their advantages of high ...
Mar 01, 2016nbsp018332In 1976 he tested the first prototype of what would come to be the best known centrifugal concentrator in the world. The product spoke for itself with the results achieved, and with some mechanical fine-tuning the Knelson Concentrator was born.
Knelson Concentrator The Knelson Concentrator is a centrifugal bowl-type concentrator developed by Lee Mar Industries, Inc., of Bumaby, B.C., Canada Silva, 1986. The unit is essentially a high speed, ribbed rotating cone with a drive unit. Figur e 1 shows a schematic of the Knelson Concentrator with its main mechanical parts.

Mine is a typical porphyry type gold-copper deposit, with low-grade gold-bearing refractory ore. as shown in the processing result, the efficiency of recovering associated gold is very poor. In this experiment, we carry out the gravity separation experimental of the knelson concentrator, trying to provide the technical basis for improving the recovery efficiency of associated gold ore.
Copper and iron are the two main elements in the raw ore, and exist in the forms of alpha chalcocite, covelline, enargite, iron pyrite. The gangue minerals are mainly quartz, dickite, alunite and a small amount of iron oxide, etc. Gold symbiosis with other minerals closely, that is the raw ore is multi-metal gold-bearing refractory ore.
