The pulsating sluice box is a new generation of gravity separation equipment that combines the core advantages of a fixed sluice box and a jig. Primarily designed for placer gold mining, it achieves a recovery rate of over 90% for difficult-to-recover fine-grained gold, such as gross gold and thin-skinned gold. It can be used as a single unit or in parallel/series connections to adapt to different production capacity requirements, and is suitable for placer gold mines, tailings recovery, coastal placer mining, and small to medium-sized mineral processing plants.
A pulsating sluice box, also called a vibrating gold sluice box, primarily recovers heavy metal minerals such as gold, tin, and tungsten through water pulsation and gravity separation. The key to this pulsating sluice box lies in optimizing the vibration frequency and water flow velocity, allowing heavy minerals like gold to be stably enriched in the constantly fluctuating slurry while preventing the loss of fine gold particles due to caking. It can be used individually in small-scale mining operations or integrated in series/parallel into large production lines such as gold dredgers and mobile washing and beneficiation units.
Typically, the pulsating sluice box is used in conjunction with washing machines and centrifugal concentrators, suitable for the roughing and enrichment of various placer gold ores, such as river sand gold and impact gold, effectively recovering free gold particles of different sizes. Furthermore, the pulsating sluice box features simple operation, low energy consumption, easy maintenance, environmental friendliness, and a high recovery rate, and is currently widely used in various placer gold mines, gold dredgers, and river gold panning production lines. The entire sorting process requires no chemical additives and relies solely on gravity and hydraulic forces, making it an environmentally friendly and highly efficient gold recovery tool.
Pulsation Mechanism:
Eccentric wheel + connecting rod design, which can adjust the pulsation frequency and amplitude.
Strip Bed Surface:
V-shaped or serrated grooves to enhance mineral retention capacity.
Wear-resistant Tank:
made of rubber or polyurethane, corrosion-resistant.
Incline Adjustment Device:
manual/hydraulic adjustment of slope to optimize sorting efficiency.
1. Low installation height design: The compact overall structure requires minimal installation height and can be directly integrated into mobile ore processing units or gold dredgers, eliminating the need for complex civil engineering foundations.
2. High fine-grained gold recovery rate: Recovery rates of over 90% can be achieved for difficult-to-recover fine-grained gold, such as coarse gold and thin-skinned gold.
3. Low maintenance costs: No complex transmission components; only periodic checks of the vibration mechanism and grid wear are required.
4. No caking issues: Periodic agitation of the bottom plate keeps the ore layer loose, completely solving the problems of easy caking and high fine-grained gold loss associated with traditional sluices.
5. Low Energy % Water Consumption: Energy consumption per unit processing capacity is only 1/3 that of a jig, and water consumption is only 60% of that of a traditional sluice box, significantly reducing production and operating costs.
6. High Reliability: Simple overall structure with no complex precision parts, resulting in a low failure rate and long service life.
7. High Adaptability: The length can be extended (1~4m) according to production scale, or multiple units can be designed for parallel or series operation, flexibly expanding processing capacity. It can also be equipped with a wheeled chassis, suitable for mobile gold mining operations.
8. Environmentally Friendly: Completely physical sorting, with no wastewater pollution, meeting international green mining production standards.
The core sorting mechanism of the pulsating sluice box is based on the density differences of mineral particles, combining water flow and mechanical agitation to enrich heavy minerals. It primarily utilizes a motor-driven eccentric wheel to generate regular mechanical vibrations, while the water flow creates pulsed ripples on the inclined trough surface. After the sluice enters the trough, high-density minerals settle to the bottom grid or grooves due to gravity, while lighter waste rock is washed to the end by the pulsating water flow. Finally, the concentrate is collected manually or mechanically.

It is primarily used for heavy minerals with a density greater than 4 g/cm³, such as placer gold, tungsten, and tin. It can also be used for ilmenite, chromite, etc. If the ore has a high mud content, it is recommended to pre-wash, screen, and deslime it.
A pulsating gold sluice box, on the other hand, uses a combination of vibration and pulsating water flow to keep the mineral layer in a dynamically loose state, significantly improving the capture rate of fine-grained gold. Furthermore, its adjustable amplitude and slope can flexibly adapt to different mineral types, making it more adaptable. A regular gold sluice box relies on a fixed water flow, resulting in a low recovery rate.
The standard model has a throughput of 20-30 m³ per hour. The specific capacity depends on the ore density, feed concentration, and target mineral particle size. Ultrafine powders (<0.1mm) require a shaking table or centrifuge.
Operating the pulsating sluice box is extremely simple. Key adjustments, such as water flow speed and tilt angle, can be mastered with just 1-2 days of training. We provide detailed operating instructions and support remote guidance and debugging to ensure users can quickly get started.
Yes! This pulsating sluice box can be paired with a circulating water system, which can reduce water consumption. It is recommended to equip it with a sedimentation tank in arid regions to achieve water reuse.
