Heng An STL80 gold concentrator
STL concentrator is kind centrifugal concentration equipment. It not only used 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.
For now, five models have been developed. Beneficiation test shows that the recovery can be 99%, especially for recovering the natural lode ore gold, when 65% Grind size are smaller than 0.074mm, the recovery is expected up to 98%. For 0.004mm size natural gold, the recovery is 97%.
The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.

"We have installed a 12, 20 and 30" Heng An concentrator at the Gold Mine in Sudan to increase our gravity gold recovery. We are the first mine there to trial the HA Knelson to recover gold and unoxidised sulphides post bacterial oxidation. Very happy with the service from you."
"I was commissioned by CRA to investigate the gravity gold recovery options for the Kolien Gold Mine in Indonesia. After exhaustive testwork we trialled a 30" manual unit with great success. We then installed 5 x 30 inch auto units and recovered approximately 7 tonnes of gold per annum from the units. Absolute Bonanza!"
