Gold recovery equipment from Qingzhou Mingxu Supply Chain is used for alluvial gold extraction, river sand washing, tailings reprocessing, and fine gold separation. The machines operate through water screening, gravity separation, vibration classification, and centrifugal force to separate gold particles from gravel, silt, and other impurities. They are designed for use in rivers, river beaches, tidal flats, tailings ponds, and shallow-water mining areas.
| Equipment Type | Working Principle | Typical Use |
|---|---|---|
| Alluvial gold washing plant | High-pressure water flushing with layered screening and gravity separation | Large-volume river sand processing and preliminary gold recovery |
| Mobile gold mining machine | Integrated traveling, screening, and collecting functions | Narrow mining zones, mountain streams, scattered small sites |
| Vibration gold screening equipment | High-frequency vibration classification with layered gravity separation | Fine-grained alluvial gold and high-mud raw sand |
| Centrifugal gold separator | High-speed centrifugal force for fine particle separation | Ultra-fine gold and heavy mineral purification, tailings recovery |
In addition to gold mining machines, the company supplies related water engineering equipment. Cutter suction dredgers and jet suction dredgers are used for river dredging and sediment removal. Water hyacinth and duckweed harvesters clear floating aquatic plants, while multi-functional salvage boats collect floating debris. These units can be used independently or combined with gold mining equipment for projects that involve both dredging and mineral recovery.
The equipment is built with wear-resistant parts at points that contact sand and slurry. Modular construction allows disassembly for transport and reassembly at remote sites. Gold washing machines and centrifugal separators can be arranged in sequence to improve recovery of both coarse and fine gold. For projects that include sand extraction and gold recovery, the dredging and washing stages can be connected to operate as a continuous line, reducing the need for intermediate material handling.
Q1: How do I choose between an alluvial gold washing plant and a mobile gold mining machine?
A1: An alluvial washing plant is suitable for fixed or semi-fixed sites with large raw sand volumes. A mobile machine is better for scattered or narrow sites where relocation is frequent. The choice depends on site size, raw material volume, and access conditions.
Q2: Can gold mining equipment be connected to an existing dredger?
A2: In many cases, yes. Gold washing and screening equipment can be installed downstream of a sand dredger. The discharge pipeline and power supply should be planned in advance to ensure the slurry can be fed directly to the washing stage.
Q3: What is the purpose of a centrifugal separator in gold processing?
A3: A centrifugal separator is used for fine gold recovery after the initial washing stage. It captures ultra-fine gold and heavy minerals that ordinary screening and gravity equipment may miss, improving the overall recovery rate.
Q4: What maintenance do these machines require during continuous operation?
A4: Regular checks include screen wear, pump performance, and the condition of water spray nozzles. The centrifugal separator should be checked for drum lining wear. A spare parts list is provided with each order based on the expected operating hours.
Qingzhou Mingxu Supply Chain Co., Ltd. is located in Qingzhou, Shandong Province, and holds qualifications in supply chain management, full-category machinery sales, and import/export. The company supplies gold mining and water engineering equipment for both domestic projects and overseas buyers.
