Introduction
Placer gold mining is the most common and cost-effective gold extraction method for river and alluvial deposits. Traditional single fixed sluice box faces obvious drawbacks such as material clogging, low fine gold recovery rate, and poor screening effect for mixed gravel ores. To solve these pain points, the matched combination of vibrating screen + shaking sluice box + fixed sluice box has become the mainstream standard configuration for modern small and medium-scale placer gold washing plants worldwide.
This integrated gold washing system realizes graded screening, anti-clogging gravity separation and multi-stage gold recovery, greatly improving the utilization rate of raw ore and fine gold capture efficiency. It is widely applied in gold mining projects in Africa, South America, Oceania and Southeast Asia.
1. Pre-screening by Vibrating Screen
Raw river sand and gravel ore is fed into the vibrating screen. Through mechanical vibration and water flushing, the screen
2. Fine Gold Recovery by Shaking (Vibrating) Sluice Box
3. Secondary Concentration by Fixed Sluice Box
Different from static fixed sluice boxes, the shaking sluice box generates continuous slight vibration during operation. The vibration prevents fine ore and mud from accumulating and clogging the chute groove, keeping the gold-catching mat in a loose and permeable state. It can effectively capture micro fine gold and free gold particles that are easy to lose in traditional sluice equipment, greatly improving the overall fine gold recovery rate.
The ore slurry flowing out of the shaking sluice box enters the fixed sluice box for secondary gravity separation. The fixed sluice box stabilizes the water flow and ore layer, further intercepting residual coarse gold and heavy mineral particles. The multi-stage separation mode minimizes gold loss and maximizes mining benefits.
Core Advantages of The Combined Gold Washing Equipment
1. Ultra-high Fine Gold Recovery Rate
The combination of vibration screening and vibrating separation solves the industry problem of difficult recovery of fine gold below 0.1mm. Compared with a single fixed sluice box, the comprehensive gold recovery rate can be increased by 15%-30%.
2. Anti-clogging & Low Maintenance
The vibrating operation of the screen and sluice box avoids material compaction and chute blockage. No frequent manual cleaning is required, reducing manual labor costs and improving continuous working efficiency.
3. Simple Structure & Easy Installation
The whole set of equipment has an integrated modular design, no complex assembly and no professional foundation required. It can be put into production quickly after on-site placement, suitable for mobile and fixed mining sites.
4. Low Operating Cost & Energy Saving
The equipment runs with low power consumption, no consumable parts, and long service life. It is very suitable for small and medium-sized mines with limited budget and simple on-site conditions.
5. Customizable Configuration
We can configure equipment of different specifications according to customer’s ore type, feeding particle size, hourly processing capacity and site environment to meet personalized mining production needs.
Applicable Mining Scenarios
- River channel alluvial gold mine, sand gold washing and separation
- Small and medium-scale open-pit placer gold mining projects
- Gold tailings secondary recovery and reprocessing
- Mining projects in remote areas with simple infrastructure
Technical Matching Tips
For better production efficiency, the feeding particle size of the system is controlled within 0-20mm after screening. Customers can match water pumps and diesel generators according to local water volume and power conditions to realize 24-hour continuous production. This complete set of gold washing equipment is the most cost-effective entry-level solution for new gold mining projects.
