Gold Centrifugal Concentrator JXSC Machine

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.

What is a Knelson Concentrator?

A Knelson concentrator is a centrifuge device used primarily in gold mining. The device is a gravity concentration apparatus, which retrieves pieces of fine gold from ore without having to use gold cyanidation, an expensive process that uses chemicals to extract gold from ore. By bypassing this process, Knelson concentrators have become a major type of mining equipment utilized by some of
