Gold dredgers serve as the central integrated equipment for alluvial gold extraction in water bodies, enabling full-cycle operations covering "excavation-conveying-separation-tailings discharge." Leveraging years of expertise in mining equipment R&D, Qingzhou Jinqi Mining Machinery Co., Ltd. has developed two major product lines—chain bucket gold dredgers and cutter suction gold dredgers—tailored to diverse mineral layer characteristics, water conditions, and mining scales, ensuring precise alignment with multi-scenario operational demands.
What is a Chain Bucket Gold Dredger?
A chain bucket gold dredger is the top choice for large-scale mining of hard mineral layers. Equipped with buckets ranging from 0.2 to 1.5 m³ in capacity, it achieves a processing rate of 50–500 m³ per hour and can penetrate mineral layers with high cobblestone content, operating effectively in water depths of 8–15 meters. Its three-stage separation system ensures a gold recovery rate of 88%–95%, while its cold-resistant design allows operation in low-temperature environments. The dredger requires only 3–5 operators for efficient handling.
What is a Cutter Suction Gold Dredger?
A cutter suction gold dredger is a high-efficiency solution for deep-water, soft mineral layer mining. It combines cutter head crushing with slurry pump suction, achieving a maximum suction depth of 30 meters and an hourly sand extraction capacity of 100–800 m³. Its pontoon-based hull design ensures flexible relocation, while the recovery rate for fine gold particles reaches 85%–92%. The dredger is also resistant to seawater corrosion, making it ideal for marine or brackish water environments.
How to Choose a Gold Dredger?
For large-scale mining in hard, shallow-water zones, opt for a chain bucket gold dredger.
For deep-water, soft mineral layers or medium/small-scale flexible operations, choose a cutter suction gold dredger.
