Rotary Scrubber + Vibrating Sluice + Sluice Box Placer Gold Processing Plant
Placer gold deposits are widely distributed in riverbeds, floodplains, ancient river channels, deserts, and other sedimentary environments. However, the characteristics of alluvial gold ore can vary significantly. Clay content, particle size, gold liberation, and the proportion of fine gold can all directly affect recovery performance.
To achieve effective washing, classification, and gold recovery, a processing plant combining a Rotary Scrubber + Vibrating Sluice (Pulsating Sluice) + Sluice Box provides a practical, reliable, and economical solution for many types of placer gold operations.
This combination integrates efficient ore washing, strong gold recovery, and simple gravity concentration into one complete processing system.
The first stage of the production line is the Rotary Scrubber, which is mainly used for washing placer gold ore containing clay, mud, sticky soil, or cemented materials.
During operation, the ore enters the rotating drum and is continuously lifted, dropped, rubbed, and washed by water. The combined action of mechanical friction and water effectively breaks up clay and agglomerated material, allowing valuable gold particles to become fully liberated.
The main advantages of the Rotary Scrubber include:
For placer deposits with high clay content, effective washing is often one of the most important factors affecting final gold recovery. The Rotary Scrubber provides a clean and properly prepared feed for the subsequent recovery equipment.
After washing and preparation, the gold-bearing material enters the Vibrating Sluice, also known as a Pulsating Sluice.
Compared with a conventional stationary sluice, the vibrating or pulsating action helps continuously loosen and rearrange the material bed. Heavy gold particles can settle more effectively into the recovery zone, while lighter gangue materials are carried away by the water flow.
This dynamic separation process offers several important advantages:
The Vibrating Sluice is especially valuable when the placer deposit contains a mixture of coarse gold, fine gold, and heavy minerals. Its pulsating action improves the working conditions of the recovery surface and provides an additional recovery advantage compared with conventional static sluice systems.
The Sluice Box serves as an additional gravity recovery stage. As the slurry flows through the sluice, gold and other heavy minerals settle into the riffles or recovery media because of their high specific gravity, while lighter waste materials continue downstream.
The Sluice Box provides several important benefits:
By combining a Vibrating Sluice with a conventional Sluice Box, the system can create a multi-stage recovery process. Gold that is not captured during the first recovery stage has another opportunity to be recovered downstream, helping reduce overall gold losses.
This equipment combination creates a complete processing route from ore washing → clay disintegration → gold concentration → secondary gold recovery.
The major advantages include:
The system can process many types of placer gold ore, including river sand, alluvial deposits, floodplain deposits, ancient river deposits, colluvial materials, and clay-rich gold-bearing soil.
The combination of pulsating gravity recovery and conventional sluice recovery provides multiple opportunities to capture gold particles, especially when the ore contains a wide range of gold particle sizes.
The production line has a relatively simple structure and can be operated with fewer complicated control systems. This makes it suitable for small, medium, and large placer gold mining projects.
The processing capacity and equipment arrangement can be designed according to ore characteristics, feed size, clay content, gold particle size, water availability, and production requirements.
Additional equipment such as vibrating screens, trommel screens, centrifugal concentrators, jigs, and shaking tables can also be integrated into the system when higher recovery or further concentration is required.
The Rotary Scrubber + Vibrating Sluice + Sluice Box processing plant is suitable for:
Because placer deposits vary greatly from one mining location to another, equipment selection should be based on actual ore characteristics and gold particle distribution. Proper washing, screening, and recovery equipment configuration can significantly improve plant performance and reduce gold losses.
