High efficiency gold knelson centrifugal concentrator
Gold Knelson concentrator is a type of gravity concentration equipment, mainly 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. It’s an ideal gravity method equipment to replace amalgamating,
mercury and cynide chemical.
Working principle
Knelson gold centrifugal concentrator is also called Nelson centrifuge, used to collect free gold in the
rein gold ore or alluvial placer gold. It’s an ideal gravity method
equipment to replace amalgamating, mercury and cynide chemical. It
use the eccentric gravity powder to collect the free gold inside
the inner cone groove. The real application results show that the
recovery can be as high as 80%, especially for the free gold in the
alluvial gold in the placer gold ore. The recovery rate for the
gold ore slurry of 0. 074mm out of the ball mill can also reach
more than 70%.

The centrifugal usually works together with the gold grinding mills
like ball mill, wet pan mill or chillean mill to be fed with gold
ore slurry and select the free gold or big size gold, the remaining
gold will be discharged and goes to the shaking table or gold
sluice so that the tailing gold can be reselected.
