Product Description

High efficiency gold knelson centrifugal concentrator


The automatic Discharge Centrifugal Gold Concentrator uses a centrifugal field to concentrate fine, free minerals that are not recoverable using the traditional techniques of small scale and artisanal miners.
For now, five models have been developed. Capacities range from laboratory scale to 150 tons of solids per hour. Beneficiation test shows that the recovery can be 99%,especially for recovering the natural lode ore gold,when 65% Grind size are smaller than 0.074 mm ,the recovery is expected up to 98%.For 0.004 mm size natural gold, the recovery is 97%.

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%.

Customer working site

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.
