What is Small Sand Gold Ore Processing Plants?
Most small and medium-sized mines face prominent beneficiation problems: scattered equipment configuration, unreasonable process flow, mismatched front and rear equipment capacity, serious fine mineral loss, low concentrate grade, unstable production and high manual operation cost. Simple equipment stacking cannot form a closed-loop production system, resulting in low resource utilization rate and poor project economic benefits.
Our Complete Ore Beneficiation Production Line provides integrated EPC solutions including process design, equipment supporting, site layout, installation and commissioning. According to different ore properties (metal/non-metal, magnetic/non-magnetic), we flexibly match flotation, magnetic separation, gravity separation and other core processes. The whole line realizes automatic feeding, continuous processing and closed-circuit circulation, effectively improving mineral recovery rate and concentrate grade, reducing operating costs, and helping mines achieve high-efficiency and standardized beneficiation production.
Complete Mini Sand Gold Processing Flow
Different from hard rock gold ore, sand gold belongs to monomer free gold with simple impurity composition. The small processing plant adopts a simplified and efficient four-stage core process: Feeding → Washing & Screening → Gravity Separation → Gold Concentrate Collection, no chemical reagents, green and environmentally friendly.
1. Uniform Feeding Stage
Raw sand gold ore mixed with soil, stones and mud is evenly sent to the processing system by a vibrating feeder or small hopper. The feeding speed is adjustable to avoid material accumulation and overflow, ensuring stable and continuous subsequent washing and separation, and improving overall processing efficiency.
2. Mud Washing & Screening Stage
Equipped with small rotary gold washing trommel screen. High-pressure water spray thoroughly washes clay and mud wrapped on sand gold particles. At the same time, large stones, gravel and waste impurities larger than gold particles are screened and removed. The cleaned qualified sand-gold mixture enters the gravity separation link to avoid impurity interference.
3. High-Precision Gravity Separation Stage
Using the specific gravity difference between gold and sand, high-efficiency gravity separation equipment processes fine sand gold. High-density gold particles sink and are collected, while low-density sand, silt and light impurities are discharged as tailings. This physical separation method realizes zero reagent pollution and effectively captures fine gold particles above 0.074mm.
4. Concentrate Collection & Tailings Discharge Stage
The separated high-purity gold concentrate is centrally collected through the material outlet. Tailings are automatically discharged without stacking blockage. The whole process runs continuously, realizing one-stop processing from raw sand ore to finished gold concentrate, greatly improving sand gold recovery efficiency.

Core Product & Project Advantages
1. Ultra-Low Investment & Fast Return
Compared with large fixed gold processing plants, the mini sand gold line saves a lot of civil construction and equipment costs. It features low one-time investment and low daily operating cost. With stable gold output and high recovery rate, the project has short payback period, extremely suitable for small-budget gold mining investors.
2. Portable & Movable, Flexible Mining
The whole plant adopts modular integrated design, with small floor space and overall movable support. It can be quickly disassembled, transported and reinstalled when the mining point is replaced, solving the problem of fixed-site limitations of traditional beneficiation lines and adapting to scattered sand gold mining scenarios.
3. High Fine Gold Recovery Rate
Optimized water washing and gravity separation process thoroughly solves the problem of fine gold loss in simple manual washing. It can effectively recover coarse gold, medium gold and fine granular gold, with comprehensive sand gold recovery rate up to 85%-92%, greatly improving resource utilization and mining profit.
4. Simple Operation & Low Labor Cost
The automated integrated process requires no professional mining technology. Only 1-2 workers can complete feeding, inspection and discharging work. The intelligent simple control system reduces operation difficulty and labor input, saving long-term labor management costs.
5. Green Physical Processing & Zero Pollution
The whole production line adopts pure physical water washing and gravity separation, without adding any chemical flotation reagents. Equipped with circulating water system, it realizes repeated water use, no sewage discharge, no environmental damage, fully meeting global small mining environmental protection standards.
6. Wide Application & Strong Adaptability
Suitable for river sand gold, beach placer gold, shallow alluvial gold and tailings secondary gold recovery. It can adapt to ores with high mud content and mixed particle sizes, and supports capacity customization of 5TPH, 10TPH, 20TPH and 50TPH, covering all small-scale sand gold mining demands.
