A gold sluice box is a traditional yet highly efficient equipment for gravity-based gold recovery. Its core function is to separate gold particles from sand, soil, and other impurities using the force of water flow and gravity. It consists of a long, inclined trough with baffles, riffles, or gold-catching mats inside, which efficiently capture gold particles while allowing lighter waste materials to be washed away. The sluice box is simple in structure and easy to operate, making it suitable for small-scale river or manual gold panning operations. It can also be used in conjunction with screening, washing machines, centrifugal concentrators, and shaking tables to improve overall gold recovery rates. It is ideal for small to large-scale placer gold mining, serving as a primary separation device. It can also be used for the secondary recovery of residual gold in tailings from gold processing plants, improving resource utilization.
