Product Description

Placer Gold ore Gravity Separator Nelson Gold Centrifugal Concentrator   

Centrifugal Concentrator is an efficient equipment for recovering free gold in all particle size ranges, specially for recovery of fine gold.

Gold centrifugal concentrator  application
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.
A).Hard Rock Mining: (No Chemicals Required) - NO Mercury, NO Cyanide
B).Alluvial / Placer Deposit Mining & Dredging
Primary gold processing when you know your gold is too fine for a sluice
Reprocessing years of old fine mineral concentrates
Processing daily sluice box fine mineral concentrates
C).Enriching/Upgrading Fine Mineral Concentrates
Classifying and upgrading sluice concentrates
Upgrading concentrates for regional processing
D). Prospecting / Drilling / Bulk Sampling 

What is the nelson gold centrifugal concentrator working principle:
In operation, material is fed as a slurry of minerals and water into a rotating bowl that includes special fluidized grooves or riffles to capture the heavies.
Fluidized water/back wash water/recoil water is introduced through the multiple fluidization holes in the inner cone to keep the bed with heavy minerals. Fluidized water/back wash water/recoil water plays an important role during the separation. 

Periodically, heavy particles(big gravity heavy minerals such as gold,iron etc) are trapped in the grooves/riffles/gratings/ribs while the light particles(small gravity light fine minerals such as sand) are washed away upward into the tailings.
 
The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.
If the water pump is connected to the control box, the feeding water,back wash water, machine start and stop, and the concentrates discharging can all be controlled automatically by the control box.
