small gold mining application machine/chinese small gold panning machine/gold concerntating machinery

Our concentrator is Knelson Type Concentrator. 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.

It is an efficient equipment for recovering free gold in all particle size ranges, specially for recovery  of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation, and recover gold from the old tailings.

Three models are available. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of — 0. 074mm, the recovery for the natural gold is expected up to 98%. For those natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. Our equipment is patented in China.

Application shows that the recovery can be as high as 99%, and the concentrating ratio is up to 1,000 times. In recovering the natural gold in lode ore with size -0. 074mm, the gold is up to 98%, For 0.004mm in particle size, the gold recovery is 97.5%.
