Spiral Concentrator Interface Monitoring Through Image ...

Spiral concentrators are robust gravity separation devices that allow for concentration of slurry streams. Optimal splitter position (which determines recovery and grade) is dependent on the interface positions of the concentrate, middlings and/or tailings in the trough.

the tailings. Unfortunately, such separations are never perfect, and in practice some waste material is included in the concen-trates and some gold remains in the tailings. Middlings, par-ticles that belong in either the concentrate or the tailings, are also produced, further complicating the situation.

These Gravity Concentrators Are Great At Gold Recovery

This gold would normally be lost to tailings, but the UF has the power necessary to recover the gold from this carbon-gold slurry. No other gravity concentrator is efficient enough to separate these ultrafine particles. Using up to 600Gs of force, the Falcon UF Gravity Concentrator can recover and upgrade particles as fine as 3 micron.
