Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are

The Knelson centrifugal concentrator is often arranged at the outlet of the ball mill, we analysis the ball mill discharge firstly, to know the metal distribution of different particle sizes. As can be seen in the above table, the major particle size is 0.045mm-0.6mm, with 75.26% of productivity, and the distribution rate of gold is up to 83.76%.
Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times.
