Process Description
The STAR TRACE Concentrator is specifically designed for recovery of free, metallic gold, platinum or silver from hard rock circuits and is also an ideal technology for alluvial gold including secondary. Recovery from sand and gravel operations.
The STAR TRACE Concentrator subjects the material Being processed to a centrifugal field of up to 60G ’s which allows recovery of finer native metals than with conventional gravity concentration equipment.
Periodically, the high grade concentrate is removed from the concentrate cone during the rinse cycle. The rinse cycle time is typically less than 20 minutes per cycle. Optimum operating cycles will range from 1hr to 4hrs.
Feed is screened at approximately 2-4mm depending on the application, introduced as slurry through the central vertical feed pipe and accelerated by the rotor. Rapid stratification according to specific gravity occurs as the material is driven up the grid concentrate cone wall under the influence of an immense gravity field.
Fluidization water is injected through the rotor wall to create a dilated or fluidized bed. The high specific gravity gold or other target particles become embedded in this zone and are retained here until the machine is stopped and the concentrate is rinsed down through the concentrate discharge ports.
A centrally located rinse manifold directs jets of water to thoroughly rinse concentrate from the retention zone after each operating cycle.
How does STAR TRACE Concentrator Work
- Fluidization water is introduced into the concentrate cone through a series of fluidization holes.
- Feed slurry is then introduced through the stationary feed tube and into the concentrate cone. When the slurry reaches the bottom of the cone it is forced out ward and up the cone wall under the influence of centrifugal force.
- The slurry fills searching to capacity to create a concentrating bed. Compaction of the concentrating bed is prevented by fluidization process.
- 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.
- Upon conclusion of the concentrate cycle, concentrates are flushed from the cone into the concentrate a under through port.

- The preparation and pre-check before startup.
- Prepare and check before startup according to the operating requirement.
- Check whether the degree of tightness of V belts is appropriate.
- Check whether the moving part is no intervening to each other.
- Check whether the Concentrated is charge pipe is closed.
Start the equipment
- Follow the requirement of the preparation and pre-check before startup, then, turn on the power supply. Make sure the running orientation of electromotor is the same as red arrow head on the outside of launder and every part does not interfere each other. All after that, you can turn on the power supply and the equipment is under the natural running.
- Feed the slurry Open the fluidization water valve when the equipment working normally, mean while, feed the slurry which confected under the required proportion of liquid and solid.
- Attention when the equipment is working
- Under the working requirement of electromotor, watch the temperature and current.
- Make sure that every moving parts are working normally.
- Pay attention to the proportion of liquid and solid of slurry at any time, adjust it in time.
Stop the equipment
