JXSC gold sluice box is a time-tested and widely used gravity separation device in gold mining. It primarily utilizes the density difference between gold and gangue minerals such as sand and gravel, using water flow to achieve efficient separation. It can effectively recover gold minerals in various forms, from coarse particles to fine gold, with an average recovery rate of over 90%. Sluice boxes can be integrated with washing machines, shaking tables, or centrifugal concentrators to form a complete placer gold mining production line, enabling automated continuous operation. Due to its simple operation, low cost, lack of need for electricity, and its customizable length, it has become a common tool for individual gold panning and placer/alluvial gold mining.
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.
The JXSC gold sluice box is manufactured from wear-resistant and corrosion-resistant materials, ensuring both durability and ease of transport in the field. Adding special liners (such as blankets, rubber mats, or corrugated plates) improves the recovery rate of fine gold, making it one of the key pieces of equipment for cost-effective and efficient placer gold mining. Blankets are particularly effective at capturing fine gold, while corrugated plates are suitable for recovering coarser gold particles; users can switch between them as needed. It is especially suitable for use in remote mining areas with complex terrain and limited power supply. Furthermore, by adjusting the angle of the gold sluice box and the water flow rate, it can adapt to the recovery needs of different gold particle sizes, ensuring that both coarse and fine gold are effectively captured.
Lightweight Frame:
Aluminum alloy or steel construction balances strength and portability.
Inclined Tank:
The tilt angle of the tank can be flexibly adjusted by means of a support or hydraulic device to control the water flow speed and optimize sorting efficiency.
Wear-resistant Lining:
The bottom of the trough is lined with rubber mats, corrugated steel plates, or special coatings to extend its service life.
Diseño modular:
Easy to assemble, the segmented design facilitates disassembly and transportation, and the tank body can be extended to accommodate large-scale operations.
1. Simple structure: Modular design facilitates transportation and on-site assembly; it can be operated without complex installation or technical training, reducing operating costs and equipment maintenance difficulties.
2. Low-cost investment: Compared with other equipo de separación por gravedad, gold troughs have a simple structure and low manufacturing cost, making them suitable for initial investment by small and medium-sized mining enterprises and individual miners.
3. No electricity required: Purely water-powered, suitable for remote mining areas without electricity supply.
4. Easy to transport: Small gold sluice boxes are lightweight and compact, allowing for flexible relocation to different work sites, making them suitable for field exploration and mobile operations.
5. Scalable application: Multiple tanks in parallel can increase processing capacity, meeting the needs of small, medium, and large-scale production, and improving recycling efficiency.
6. Energy-saving and environmentally friendly: Gold separation is achieved solely through natural water flow, avoiding environmental pollution and conforming to the principles of green mining.
The working principle of a gold sluice box is based on the combined action of gravity sedimentation, and water flow separation. The main body of the device is an inclined trough, with a rough lining (such as corrugated plates, blankets, or grass mats) laid on the bottom. The ore sand mixed with water flows in from the upper end of the trough. The water flow carries the lighter sediment downwards, while the heavier gold particles settle in special baffles (such as riffles or felt mats) or grooves at the bottom of the trough due to gravity. The sediment is washed away, and the gold concentrate is obtained by periodically cleaning the bottom of the trough.

Sluice boxes are primarily suitable for alluvial gold deposits, especially riverbed and riverbank placer deposits containing coarse gold particles. If the ore contains a significant amount of clay, pre-washing is recommended to prevent clogging. For vein gold deposits, the ore needs to be crushed and ground before being used in conjunction with other gravity separation equipment.
Yes. For example, for ore containing a mixture of coarse and fine gold particles, coarse gold can be recovered first using a sluice box, and then fine gold can be recovered using a concentrador centrífugo o mesa vibrante, thus maximizing resource recovery.
For small-scale operations, only a water pump or natural water source is needed. In large-scale gold processing plants, however, vibrating screens, ore washing machines, and gravity separation equipment are required to form a one-stop gold wash plant or complete production line.
These include the angle of the sluice box, water flow velocity, lining type, ore particle sizey feed concentration. Parameters need to be adjusted on-site based on the characteristics of the ore to achieve the optimal recovery rate.
You can lay blankets or grass mats on the bottom of the sluice box to slow down the water flow and increase the settling time of fine gold. At the same time, reducing the angle of inclination of the sluice box will extend the residence time of the ore in the box.
