GeoSluice - Colorado River SluiceEngineered for superior fine gold recovery and high volume production. The innovative design features a dual flare system that sets a new standard in gold capture. By constricting water flow after the initial flare, we maximize washing time and initiate the first stage of gold separation. The strategically engineered back pressure in the sluice's midsection further enhances gold settling. Finally, the second flare creates a precise drop in water
