Product Description
STL30 Nelson Gold Centrifuge for Alluvial Gold and Milled Rock Gold Dust
What is the Description of nelson gold centrifuge?
A.Working environment:
For now, five models have been developed. Capacities range from laboratory scale to 150 tons of solids per hour.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 developed polyurethane liner on the stainless steel concentrating cone.Polyurethane concentrating cone is durable and every polythane ring can be replaced if wear out.
What is the Application of nelson gold centrifuge?
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 Structure&Working Principle of our nelson gold centrifuge?
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.
