  • These Gravity Concentrators Are Great At Gold Recovery

    However, during the flotation process, extremely fine gold particles will float with the carbon. 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 ...
