STLB concentrator is kind centrifugal concentration equipment. 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. 


Since 1985, three models have been developed. 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 that 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. 

 

How does STLB Concentrator Work 
1. Fluidization water is introduced into the concentrate cone through a series of fluidization holes. 
2. Feed slurry is then introduced through the stationery feed tube and into the concentrate cone. When the slurry reaches the bottom of the cone it is forced outward and up the cone wall under the influence of centrifugal force. 
3. The slurry fills each ring to capacity to create a concentrating bed. Compaction of the concentrating bed is prevented by fluidization process. 
4. The flow of water that is injected into the rings is controlled to achieve optimum bed fluidization. High specific gravity particles are captured and retained in the concentrating cone. 
5. Upon conclusion of the concentrate cycle, concentrates are flushed from the cone into the concentrate launder through port.
